US Approves $75 Million Taiwan Tactical Data Link Upgrade


US Approves $75 Million Taiwan Tactical Data Link Upgrade

While it is to be competed, the ATDLSU program looks like a lock for Lockheed Martin, who had the original PoSheng program which upgraded all three services of Republic of China [Taiwan] (see video below), from 2003 to 2012. I worked on an Opnet full network model of the PoSheng network under CACI.

The Lockheed Martin Po Sheng team also included key companies throughout the United States. California-based companies include ViaSat located in Carlsbad and CACI International, Inc., Titan, Information Networking Systems, Inc., and Digital Wizards in the San Diego area. Other team members include Alion Science and Technology, Annapolis, Maryland; Veridian Engineering Group, Arlington, Virginia; and Austin, Texas-based Advance Programming Concepts, Inc., all of whom supported data link processing, developmental test, evaluation and network design.

I doubt they'll be able to pull the old team together, as ViaSat has sold off their tactical data link business to L3Harris.

The US State Department has approved the possible sale of the Advanced Tactical Data Link System Upgrade Planning and related equipment to Taiwan.

The estimated $75-million sale includes cross domain solutions, high assurance devices, GPS receivers, and communications equipment.

“The proposed sale will improve the recipient’s ability to meet current and future threats by enhancing communications and network security, and providing infrastructure to allow the secure flow of tactical information,” the Defense Security Cooperation Agency stated.

The principal contractor will be decided through a competitive process.

NATO Link-22 Upgrade

Washington last year decided to upgrade Taiwan’s Link 16 data link system to NATO’s Link-22, offering greater range and a direct connection to the US military.

Link-22 is a secure beyond-line-of-sight communications capability that interconnects “air, surface, subsurface, and ground-based tactical data systems,” Focus Taiwan wrote, citing head of Department of Strategic Planning Lee Shih-Chiang.

Chinese Sanctions US Firms

It comes as China sanctioned five US defense contractors last month in response to their arms sales to Taiwan, freezing their properties based in China.

The firms are BAE Systems Land and Armaments, AeroVironment, Viasat, Alliant Techsystems Operation, and Data Link Solutions

China 'Breathes Fire' As Taiwan Set To Acquire US-Led NATO's 'Most Advanced' Tactical Data Link System - Link 22

Parth Satam

In a significant military development that might affect how a clash between Taiwanese-American and Chinese forces pans out, Taiwan has announced it will acquire the North Atlantic Treaty Organization’s (NATO) Link 22 tactical data link systems. 

Lee Shih-Chiang, the head of the Republic of China’s Ministry of National Defense (MND) Department of Strategic Planning, made the statement at a meeting of the legislature’s Foreign Affairs and National Defense Committee. 

Data links are digital radio-based systems that interconnect multiple air and ground assets. They share each platform’s view and position and present a tactical battlefield picture. Core data regarding information and input can also be sent to multiple assets. 

Coalition militaries of various countries, like NATO, find particular utility for data links, like the predominant Link 16, which is common across nearly every American and European tactical and strategic fighting platform. 

Fallback When Chinese Jam Communications?

A report in Taipei Times said the People’s Liberation Army (PLA) is likely to jam Taiwanese radio communications through electronic warfare (EW).

Saying Link 22 “could prevent that” implies a scenario where Taiwanese fighters, ground command and control centers, and warships are not entirely cut off from each other. 

Broadly aware of the other’s position, weapons data, fuel, and the location of nearby PLA forces, they can receive further advanced information from American surveillance assets like the E-3 Sentry Airborne Early Warning (AEW), RC-135 Rivet Electronic Intelligence (ELINT) aircraft and RQ-4B Global Hawk strategic surveillance drones.

These aircraft would fly around the South and East China Seas, keeping a watch on the battlefield during a potential Taiwan crisis. 

How Advanced Is The Link 22?

The data linking and sharing are also markedly different and diverse than the Link 16 systems on some of the leading four and 4.5-generation fighters.

Link 16 merely transmits positional, fuel, and weapons payload data other fighters are carrying and some communication information in an omnidirectional fashion, spreading everywhere, with the transmission highly vulnerable to being intercepted. 

But using the Link-22 boasts greater anti-jamming capabilities and improves command efficiency while providing faster communications transmissions.  

Chieh Chung, an associate research fellow with the National Policy Foundation in Taipei, was quoted saying that Link 22 is a substantial advancement over Link 16. “It greatly strengthens anti-jamming capabilities and improves command efficiency while providing faster communications transmissions,” Chung said. 

Link 22 Tactical Data Link
Link 22 Tactical Data Link

Taiwan’s own domestically developed data link system, built by the Chungshan Institute of Science and Technology (CIST), is very broadly based on the American Link 16 and meets many of its military’s needs. 

But Link 22 allows it to tap into US military data links directly, as the latter’s assets will surely see some level of participation in a conflict with China. 

Even if it is assumed the nature of US involvement would only be complementing and secondary – logistics, arms transfers, and providing surveillance and targeting as it does for Ukraine – having access to additional surveillance and battlespace information from superior US technology gives Taiwanese commanders many options. 

Su Tzu-yun, a research fellow at Taiwan’s Institute for National Defense and Security Research, further differentiated between the Link 16 and Link 22 systems, saying the latter uses high-frequency and [the former wide band] ultra-high frequency bands that can operate long distances without a satellite.

Link-22 features an automatic grouping function that can fully map out the positions of enemy and friendly forces via a common operational picture (COP), Su said.

China’s XS-3 and DTS-03 data links are already superior to Link 16. Hence Taiwan receiving the Link-22 gives it a massive edge in tactical situational awareness. 

The Link 22’s website describes it as “beyond the line of sight (BLOS) communications” and “gap less communication across 1000 nautical miles.” [via surface ground wave HF]

Seven specific NATO member nations are a part of the Link 22 project, including the US, UK, France, Canada, Germany, Italy, and Spain.

Developed as an improvement over the older Link 11 and meant to complement Link 16, the program enhanced data exchange and provided a new layered communications architecture. 

China Unhappy

China’s Foreign Ministry and other defense commentators slammed the development, saying such arms sales do not deter China’s position on Taiwan and that the actions are meant to encircle and provoke Beijing strategically. 

Reacting to the transfer of Link 22 and the first shipment of FIM-92 Stinger man-portable air defense (MANPAD) systems that arrived on the island, Foreign Ministry spokesperson Mao Ning called it an “extremely wrong and dangerous move.” 

The report in Global Times also quoted leading military expert Song Zhongping, who pointed out that the transfer of the Link 22 essentially proves the US would be commanding and directing Taiwanese operations. This implied they were less likely to take on the Chinese military frontally. 

“The man-portable air-defense system like the FIM-92 Stinger missile has proved its lethality in urban warfare…and once Taiwan authorities obtain the Link-22 system, it means that the island will be brought under the US combat command structure,” Song said. 

At a political level, the US agreeing to give Taiwan Link 22 means the North Atlantic Treaty Organization (NATO) leadership has fully consented and is on board.

This shouldn’t be a surprise as the bloc has been trying to make inroads into Asia by enhancing cooperation with Japan and adopting a hardline on China over Taiwan, calling it a future Ukraine. 

 

A Study on the Future Development Trend of Air Data Links​

in 國防大學空軍指揮參謀學院空權與國防學術研討會論文集 (Proceedings of the Air Power and National Defense Academic Seminar at the Air Force Command and Staff College, National Defense University), issue 2021/10, p.-60

​Title: III. Development and Application of CCP Data Link Systems​

Since the first Gulf War in 1991, the Chinese Communist Party (CCP) has been developing high-intensity data link systems using information technology. Drawing inspiration mainly from the U.S. military command system, which shifted from a "vertical" information acquisition and decision command to a "horizontal" level where all military units could obtain the same intelligence, the CCP recognized the importance of data link systems in the joint operations of the U.S. military. (see Note 16)

(I) Overview of Development​

The development of CCP data link systems began in the early 1980s with the HN-900 model as the initial system, initially used for tactical data processing on naval vessels and information exchange with external equipment. Due to the CCP's early push for digital informationization, the lack of integration in the research and development of the foundational design resulted from the varied needs and independent thinking of different military branches.

From the mid-1990s, the CCP established the HN-901, HN-902, and HN-903 data link systems, implementing technological and destructive capabilities in coordinated naval, air-to-air, and naval-to-land operations. Subsequent developments, such as the TJN-905 data link, marked the maturity of data link system development. During this time, the system could execute rapid responses and feedback between command centers, issuing operational commands and receiving battlefield information, establishing a complete data link system (see Figure 5).

(II) Current Capabilities​

In 2008, the CCP successfully developed the comprehensive data link and the H/TJN-906 broadband high-speed data link, aiming for a large capacity and high transmission rate. The success of this data link system signifies that CCP technology has officially moved towards the goals of large capacity and high transmission, with functionality and benefits comparable to the U.S. military's Link-16 data link. (see Note 17)

After 2020, the CCP widely equipped the DTS-03 data link (see Figure 6), which includes various data link terminals that can be configured on different mobile platforms according to actual needs. In recent years, the CCP has completed the "XS-3" tactical broadband high-speed data link architecture. This system, compared to the DS-03, enhances cooperative engagement capability (CEC), increases the transmission rate to 2M/Sec, and can construct an information distribution system for air and ground combat units. It is suitable for fighter jets, bombers, drones, and simultaneously supports high-capacity information transmission for multiple network units with anti-jamming capabilities (see Note 18).

Chinese Warships Struggle to Meet New Command, Control And Communications Needs

By James C. Bussert
Signal February 2009

Evolutionary introduction of assets leads to different combat capabilities.

China may be building a navy that features some world-class technologies aboard new ships, but its large numbers and variety of naval and air weapons still are operated in isolated methods because of the lack of effective command, control and communications and datalinks. Of 494 Chinese navy ships, the only combatant warships with credible Level III command, control and communications are four imported Russian Sovremennyi guided missile destroyers, 11 new construction guided missile destroyers, four 054A guided missile frigates, two upgraded Luda-class destroyers and 12 submarines, including nuclear strategic ballistic missile submarines.

Even these 33 vessels are handicapped by limited shore or space satellite command, control and communications (C3) support and the lack of integrated structure, organization, training and experience. The absence of technical expertise by sailors results in some computers being used as typewriters, which inhibits command and control (C2) missions. As many as 90 percent of Chinese warships have an obsolete C3 capability—or none at all.

The People’s Liberation Army Navy (PLAN) has put together a core C3 shallow-water capability by datalinking new guided missile destroyers (DDGs) with new construction Houbei catamarans and 054A frigates (SIGNAL Magazine, May 2007). However, severe limitations remain for strategic or distant operations beyond coastal waters far away from nearby C3 shore support.

This is a recent problem. Traditionally, PLAN surface warships largely conducted coastal operations and functioned without coordination and tactical data sharing between ships or shore. Communications aboard old Luda destroyers and legacy frigates were adequate. But new construction missile destroyers and frigates are aimed at newer operation areas and missions that must employ aircraft and subsurface units. PLAN ships will be faced with new blue-water sea lines of communication protection or carrier battle group missions.

Three phases of evolution have taken PLAN warships from basic communications on a single platform to combined platform C3. The first phase involved simple communications. Each weapon was stand-alone, and each ship controlled only its internal sensors and weapons. One sensor to one weapon is a classic stovepipe system. The PLAN includes 62 mine warfare, 109 amphibious, 45 surveillance, 154 support and 32 auxiliary ships. A few large new construction vessels in this group, such as the 25,000-ton LPD 071, 21,000-ton to 37,000-ton oil replenishment ships, 10,000-ton Dajiang submarine tenders or 21,000-ton Yuonwang space event ships have respectable satellite and multiband C3, but they are not battle group warships. The 494 warships include 29 destroyers, 47 frigates, 63 submarines and 355 patrol boats. A baseline is the vintage Luda destroyers and early frigates that were the PLAN mainstay from 1960 to 1980. Luda and the Jianghu frigates both had seven external high frequency (HF) antennas. Jianghu frigate antennas varied from seven-foot to 32-foot whips. Later frigates increased to more modern sensors and weapons, but they still entailed stand-alone systems and ships.

The first Chinese-built ship with no imported equipment at all was the 10,000-ton freighter Fenquing in 1974, but for decades imported equipment or copies were common. Imported Decca surface search radars, Magnavox satellite communications and Redifon marine transmitters were on many PLAN warships from the 1980s on. In 1984, the PLAN paid $15 million for Seafox integrated communications from Marconi. A contract to have the United Kingdom provide a complete upgrade to Luda in 1982 fell through because of the $375 million cost. Instead, the Luda II refit DDG 105 added a helicopter hangar and three-dimensional (3D) radar in 1987. Luda DD 132 later replaced its 3D radar with a satellite navigation antenna, probably the Russian R-793 Pritsep GPS/GLONASS operating at 4-6 gigahertz. Other 1980s Luda refits added radars and weapons but no evident C3 systems.

Some impressive long-range cruises and distant operations occurred with phase one units. Examples include the PLAN seizing the Paracel Islands from Vietnam in the South China Sea in 1974, intercontinental ballistic missile test observation in the South Pacific in 1980, and more than 20 warships conducting large naval exercises in 1988-1989 coinciding with occupation of the Spratly Islands.

Phase two entailed various shipboard sensors, control and weapons being coordinated within a single platform. The Luda III upgrades and newer frigates typify this phase. A metric of increased C3 capability in the Jianghu upgrades is indicated with five antennas on Jianghu I, eight on the Jianghu II helicopter deck upgrade and 11 whip antennas on Jianghu III gun/surface-to-surface missile (SSM) fire control and electronic countermeasures upgrade. The last two Ludas launched in 1990-1992—DDGs 165 and 166—had the Luda III upgrades that included the Tavitac combat direction system (CDS) computer and Vega II weapon control computer from France. The CDS included the French Link W—a copy of Link 11—and imported communications. The new generation Luhu DDG 112 and 113 also had Tavitac CDS installed, although the Chinese designation ZKJ-4 was used.

Though not reported in Western open sources, China’s 716 Institute is believed to have developed a first-generation C2 system of unknown designation. The Chinese claim of “wide fleet distribution” hints that this system could predate the new post-1990 051 and 052 DDGs and was on newer 053H frigates and possibly updated Luda ships. The system had two computers and a display console. It featured a Pentium central processing unit with a Compact PCI bus and an FDDI high-speed local area network with a 100-megabyte Ethernet.

This technology somewhat dates the system. A crude Chinese-developed digital fire control system—designated Type 88—was displayed publicly in 1991, the year the first Type 88 was installed on a 542-ton Houjian fast attack craft. It interfaces with gun, radar, electro-optic sensors, PL-9 surface-to-air missile and electronic warfare systems. The Houjian has no sonar or antisubmarine warfare weapons onboard. The Type 88 consists primarily of buttons and toggle-switch technology with four plug-in cards on the lower chassis.

The first of four new 1,700-ton Jiangwei frigates also was launched in 1991, and they were credited with the first computerized weapon control system, designated CCS-3 in references. It was more complex than the Type 88 because it had a datalink compared to the Type 88 point-to-point architecture. The datalink probably was the Chinese ISBC-900 series bus. Another metric to identify level II vessels is if they have a combat information center (CIC) in the architecture. The first PLAN warship claiming a CIC was the Luhai.

China’s military is backfitting low frequency (LF), very high frequency (VHF) and ultrahigh frequency (UHF) communications and upgrading existing systems to digital technology. This is achieved through the use of Western imports and indigenous radio production plants. Existing South Fleet 053H frigates are adding HN-900 two-way datalinks similar to Link 11. FF 563 and 553 added satellite communications and HN-900 for C3 but retained old HY-2 SSMs and guns. The Eastern Fleet FF 513 received the less-capable one-way HN-900 datalink.

PLAN ships and modern J-10A and J-11 aircraft use the 1553B databus for their datalinks. The PCI bus card is manufactured by Chengdu Enpht Technology Company under the name EP-H6273. Protocol chips run from 512 kilobits up to 64 megabits. The 1553B chassis and slots, named ACE 1553, are manufactured by Beijing Shenzhou Feihang Company. The first Type Houbei catamaran missile boat was launched in 2004, and 20 had appeared by 2008 (SIGNAL Magazine, December 2007). They may be replacements for the aged Hegu (Osa) and Huangfeng (Komar) boats, but that may not be true. They all have Marine Corps paint, which indicates an amphibious support role such as fire support for landings. A high automation level is hinted at by a crew of only 12, compared to a crew of 26 on earlier, similar-size Huangfeng missile boats. With only five- and seven-foot HF whips on the bridge and no satellite communications radomes, it is surprising to see an HN-900 datalink to the DDG between the four SSM cells.

Examples of shore commands controlling tactical units include the 2001 J-8 interception of the U.S. Navy EP-3 off of Hainan and the 1994 Han SSN and 1996 Song diesel boat interception of the Kitty Hawk carrier battle groups in the Sea of Japan. The use of Chinese satellites for reconnaissance, navigation and communications is likely in coastal waters, but GPS and GLONASS would be required for distant operations.

Phase three of the evolution is for major PLAN warships to have C3 with other platforms, including aircraft and other surface ships. The PLAN warships with obvious phase three capabilities are the four modern new construction DDG classes. The Sovremenny 956EM DDGs certainly are the best C3 warships in the PLAN. The next indigenous nominees are the 052C Aegis DDGs 170 and 171, and the newest 051C DDGs 115 and 116 with the S-300 air defense 30N6E1 phased array radar and SA-N-6 vertical launch surface-to-air missiles. All of these types of ships were launched in 2006.

The 956EM warships imported in 1999 had the Russian Sapfir-U combat systems and associated datalinks and communications—Bell Crown datalink and two Light Bulb video datalinks for SSMs. Fore and aft mast yardarms mount four 200-1300-megahertz UHF dipole antennas. Twelve HF whips and a 45-foot-tall MF antenna were on the aft helicopter deck. LF wire bundles extend from the forward to the aft yardarm and then down to the O-2 deck.

In 1998, Neptune exported upgraded Buran-5ke automated communication complexes to Russian customers, and this would have been on the 956EM. In 2001, Russia exported the first four Band Stand radar/datalink systems to Jiangnan Shipyard in Shanghai for the new 052B DDGs. The Mineral-3 datalink and radar operates in the I band with a 30-kilometer range. The Mineral-3 can detect up to 200 contacts and designate nine as targets for SS-N-9 or SS-N-22 SSMs. China developed the HN-900 tactical datalink transmitter that has appeared on all modern 051 and 052 DDGs, 053H guided missile frigates (FFGs) and 022 catamarans, and it has been backfitted to a few Luda DDGs.

The two 052C DDGs reportedly are the initial ships for the second-generation JY10G Chinese multimission information processing system. The JY10G uses land-ship and air radar inputs to integrate with other sensor sources and weapon systems. Reports that this system also is on the Houbei SWATH missile boats probably are not credible because the boats do not even have satellite communication radomes.

China’s Beijing Readsoft Technology Corporation has copied the MIL-STD 1553B databus under the designation GJB289A. It first appeared on People’s Liberation Army Air Force (PLAAF) J-8 and J-11 aircraft and later on the naval J-10A and on the weapon system aboard the 052C. The 051 and 052 DDGs, as well as other warships, probably will follow suit. The most valuable Russian imports—956EM DDGs, Su-30 long-range fighters and Kilo 636 diesel submarines—provide proven interplatform datalinks that China can copy or try to emulate on its own indigenous platforms. Additionally, that will enable joint Russian-China naval operations with common datalinks.

Russian/Chinese cooperation includes military geopositioning satellites. The new generation-2 of the Chinese Beidou satellite navigation system will be compatible with the Russian GLONASS. The modern PLAN shipboard Dong Zhong Dong satellite communication system is designated AKD3000 and operates at 14 gigahertz in the Ku band frequency, and it consists of 0.6-meter, 0.8-meter and 1.2-meter diameter antenna variants. Lack of high-definition digital reconnaissance satellites hampers command, control, communications and intelligence mission accomplishment, and a lack of military navigation satellites inhibits many datalinks for target position information. It is known that PLAAF Su-27s must rely on voice communications, and Su-30 MKKs have the TSK-2 datalink, but it is not on PLAN units. The newest Su-30 MK2 naval fighter aircraft exported to China have a digital TSIMSS-1 communication system. The 052B and 052C destroyers and the J-10A fighters will have datalinks similar to the Russian AT-2M, which itself is a copy of the U.S. Navy Link 16.

Submarines are the most challenging command link platforms. Strategic or tactical communications with submerged submarines primarily come from shore very low frequency (VLF) stations. Russia built LF stations at three fleet headquarters by 1976. China’s first VLF site was Lushun in 1965, and its most recent was an extremely high power site at Yulin submarine base on Hainan in 1982. The twelve Kilo diesel submarines’ digital CDS MVU-110EM and communications suite of R-625 UHF, R-680 VHF/HF to R-683 LF receiver covered all bands. Target designation for submarine-launched 3M-54E anti-surface-ship missiles can be possible by datalinks on 956EM, Su-30 fighters, helicopters and naval command aircraft. Russian Mi-24 helicopters, which are PLAN assets on warships, have Landaish analog mission computers to provide targeting data via a PK-025 datalink. Russian-provided naval air units had RSIU-5 VHF radios, which are on PLAN surface warships.

Some auxiliaries (AGI) and non-SSM ships now carry a Light Bulb antenna, indicating a functional change from a missile datalink to a high-capacity communication link similar to a Link 16. The main PLAN shore C3 commands are located at the North Fleet (Qingdao), East Fleet (Ningbo) and South Fleet (Guangzhou) headquarters with main control from the PLA Central Command in Beijing. Information integration for large DDG and naval shore commands use PIII ruggedized computers with VxWorks or Windows NT operating systems, 100-megabyte Ethernet and large, multipurpose video monitors.

U.S. Releases Advanced Tactical Data Link System Upgrade

TAIPEI - The below is a press release with edification in brackets:

(Arlington, Virginia, February 22, 2024)

The US-Taiwan Business Council today welcomed the announcement of a possible Foreign Military Sale to Taiwan of Advanced Tactical Data Link System Upgrade Planning and related equipment at an estimated total cost of US$75 million.  The Defense Security Cooperation Agency (DSCA) delivered the required certification notifying Congress of the proposed Taiwan arms sale on February 21, 2024.

The published Congressional Notification (transmittal number 24-09) is for FMS Cross Domain Solutions (CDS) [The FMS CDS is a means of information assurance that provide the ability to manually or automatically access or transfer information between two or more differing security domains.  FMS CDS devices are integrated systems of hardware and software that enable the transfer of information among otherwise incompatible security domains or levels of classification.  They also enable filtering of unauthorized messages and malicious files and, in order to protect both U.S Classified Military Intelligence (CMI) and FMS customer systems, networks and data], High Assurance devices; Global Positioning System (GPS) receivers, communications equipment, requirements analysis, engineering, technical services, and other related elements of logistics and program support.

Council President Rupert Hammond-Chambers commented, “We welcome this ongoing normalized and regularized arms sales process. But we again see a focus on sustainment, with little or no consideration of the broader challenges that Taiwan is facing - including blockade and interdiction scenarios, along with grey zone activities.  We echo incoming Indo-Pacific Commander Samuel J. Paparo’s recent U.S. Senate testimony, where he said that ‘If we’re just planning for an invasion, we’re leaving a wide range of military options unplanned for.’ ”

“The asymmetric approach is one piece of the puzzle, not the whole puzzle, and the Administration needs to broaden its approach. Our security assistance should include capabilities allowing Taiwan to respond to all its challenges, not just the threat of an invasion.  In May 2022, we commented on security assistance focused solely on a D-Day-style attack by PLA forces, citing its shortcomings.  We have consistently noted this point in previous comments on recent arms sales, which have focused almost exclusively on munitions and sustainment.”

Hammond-Chambers added, “The ongoing issues surrounding Kinmen call for a robust Taiwan coast guard that can patrol its territorial waters.  Training and interoperability should be the primary goals, along with accelerating the expansion and modernization of the Taiwan Coast Guard fleet.  Transferring existing Sentinel Class U.S. Coast Guard boats to Taiwan - while replacing the U.S. inventory with newer boats - could be one way to accomplish that.  There is precedent for this sort of ship transfer, and ongoing allocation of U.S. financial resources could absorb costs.

Blockade scenarios require anti-submarine vessels and helicopters, with larger ships required to patrol Taiwan's territorial waters.  Taiwan could build such ships in domestic yards, while sourcing subsystems internationally.  In the face of China's relentless grey zone pressure, Taiwan's burgeoning fighter fleet - which will top 200 advanced F-16s by the end of 2026 – also requires support aircraft.”

Hammond-Chamber concluded by saying “The U.S. appears to be dismissing these other challenges for now, potentially creating current and future vulnerabilities for Taiwan.”

China opens fire on Lockheed for arming up Taiwan

Jeff Pao

China has vowed to sanction Lockheed Martin, the world’s and America’s largest defense contractor, for a fifth time after Washington approved on December 16 a US$300 million arms deal that will link Taiwan’s tactical information system with that of NATO allies.

The new system will help improve Taiwan’s command, control, communications and computer (C4) capabilities and enhance operational readiness to meet current and future threats, according to the Pentagon’s Defense Security Cooperation Agency.

The arms sale was the 12th to Taiwan since US President Joe Biden took office in January 2021. 

Beijing has fired four rounds of countermeasures against Lockheed since July 2020, including placing it on an “unreliable entities list,” ordering the defense firm to pay fines equivalent to twice the amount of its arms sales to Taiwan in recent years, and banning the company’s executives and staff from entering China. 

After the US government approved Lockheed and Northrop Grumman’s arms sale to Taiwan on August 24 this year, both companies were sanctioned by Beijing on September 15, though the Chinese government did not specify the terms of the curbs at the time.

“It is true that both Lockheed and Northrop Grumman do not have a lot of direct businesses in China. But it does not mean that our sanctions against them are meaningless,” a Shaanxi-based writer using the pen name “Qiaofeng” says in an article. “Their affiliated companies are involved in many fields such as aircraft, energy and electronics in China.”

The writer says the curbs send a message to the international community that China opposes all forms of foreign interference and has the determination to safeguard its sovereignty and territorial integrity.

He says that by sanctioning the US defense contractors, China can set an example for upholding international fairness and justice amid the United States’ blatant violation of international rules.

Military operations

Two Chinese weather balloons were seen crossing the sensitive median line of the Taiwan Strait on December 17, the days after the arms sale announcement, according to the Defense Ministry in Taipei.

“The Chinese communists’ frequent military operations around Taiwan present a serious threat to us,” said the island’s Ministry of National Defense. 

The ministry said the new tactical information system will help Taiwan improve its battlefield awareness. It said it expects the sale to “take effect” in one month. 

A source told Reuters that Taiwan’s existing Syun A system, which has been in service for more than a decade, cannot easily interface with non-US equipment such as locally made fighter jets. The source said the joint warfare capabilities of Taiwan’s C4 system are inadequate.

The Syun An system is reportedly unable to integrate data from the long-range early-warning radar system situated in the island’s northern mountains.

The system’s downgraded Link 16 tactical data network is also incompatible with non-US equipment, including Taiwan’s Indigenous Defense Fighters, French-made La Fayette-class frigates and Mirage 2000 fighters. Link 16 is a standardized military tactical data link network used by the US and NATO allies.

“China will take resolute and strong measures to safeguard its sovereignty and territorial integrity and take countermeasures against relevant companies involved in arms sales to Taiwan,” said Wang Wenbin, a Chinese Foreign Ministry spokesperson. 

“The Taiwan question is entirely China’s internal affair that should not be affected by any foreign interference,” he said. “No matter how many weapons the US provides to the Taiwan region, it will neither change the historic course of China’s reunification, nor weaken the Chinese people’s firm will in safeguarding our national sovereignty and territorial integrity.”

He said the recent US arms sale to Taiwan seriously undermines China’s sovereignty and security interests, harms peace and stability across the Taiwan Strait and sends a wrong message to separatist forces seeking “Taiwan independence.” 

“China deplores and strongly opposes this and has made solemn démarches to the US side,” Wang said. 

‘Dangerous’ fighter jet intercepts

The Taiwan Strait balloon incidents come about a month after Chinese President Xi Jinping and US President Joe Biden met in San Francisco on November 15 and agreed to increase communications. 

The two leaders had an in-depth exchange of views on strategic and overarching issues critical to the direction of China-US relations and on major issues affecting world peace and development. But the leaders reached no new agreements on Taiwan-related issues, according to reports.

Biden reiterated that Washington’s “one-China” policy has not changed and that the US opposes any unilateral changes to the status quo from either side of the Taiwan Strait.

Xi reportedly told the US to stop supporting Taiwanese independence and halt arms sales to the self-governing island, which Beijing considers a renegade province that must be “reunified” with the mainland. The US side said it will continue to support Taiwan’s defense.

Admiral John Aquilino, head of US Indo-Pacific Command, told the media on December 18 that China’s “dangerous” fighter jet intercepts against US aircraft seem to have stopped since the Xi-Biden summit, which he characterized as an “incredibly positive outcome” if sustained. 

However, China’s People’s Liberation Army (PLA) continues to launch warplanes across the median line of the Taiwan Strait on a daily basis.

China spies on Taiwan's US-Made Defenses

A Taiwan Air Force Captain is the fourth confirmed person to be caught spying for China within the last two years, reported the Associated Press.

The espionage from within Taiwanese ranks focused on the nation's missile defense and communications systems built with sensitive U.S. technology.

Capt. Chiang was based in the north of Taiwan where the military houses their Lockheed Martin and Raytheon-supplied Patriot missiles along with the island's early warning radar system.

In addition, local media reports translated by the AFP in Taipei said that a retired Taiwanese agent from the Ministry of Justice Investigation Bureau is in police custody for allegedly luring his colleagues to China under the pretext of traveling or doing business. They were then forcibly detained and interrogated on sensitive information, said the Chinese-language United Daily News.

Inside information on Taiwan serves China's long-standing resolve to take back the nation by military force if necessary. The successfully modern island off the southeast coast of China remains independent and resistant to reunification with the mainland since a civil war 63 years ago.

Last year, the Taiwanese army's head of communications and information was also arrested on the charge of spying for China. Taiwanese news reported that Maj. Gen. Lo Hsieh-che was recruited by a Chinese female spy in Bangkok while he was stationed in Thailand. He gave strategic secrets to Beijing and has now been sentenced to life in prison. 

The Taiwan defense ministry said at the time that the Maj. Gen. was unlikely to have had access to U.S.-related intelligence. However, as a high-ranking officer he had documents regarding the purchase of the Po Sheng command and control system from American defense contractor Lockheed Martin.

The Po Sheng provides branches of the Taiwanese forces with a shared communication network that is crucial for coordinating military action.

In the event that China launches an attack on Taiwan for not ceding its independence, which China views as rebellious, the Chinese would want to know how to make their target as vulnerable as possible.

Having access to data on Taiwan's radar-enabled missile defenses and communications system would give China a crippling upper hand, as gaining control of the electromagnetic spectrum is a major asset in modern warfare.

SAN FRANCISCO – Albedo raised $35 million to build and launch its first high-resolution Earth-imagery satellite.

The Series A-1 investment round, led by Standard Investments, brings the Earth-observation startup’s total funding to $97 million.

The investments announced Jan. 23 will accelerate deployment of Albedo’s very low Earth orbit (VLEO) constellation. Albedo aims to “ultimately prove out and proliferate the world’s first high-resolution VLEO platform,” Albedo CEO Topher Haddad told SpaceNews by email.

10 centimeter resolution

Since Albedo was founded in 2020, the company has developed a platform to collect optical imagery with a native resolution of 10 centimeters per pixel and two-meter thermal imagery. Similar resolution is obtained by aircraft and classified reconnaissance satellites.

Albedo aims to provide commercial and defense customers with on-demand, high frequency coverage. 

“As geopolitical tensions rise and we approach an irreversible climate change tipping point, the need for innovative dual-use technologies is crucial in sustaining a safe global environment,” Haddad said in a statement.

VLEO “will open up a wide variety of exciting opportunities around enhanced imagery and data collection, which is a key unmet challenge in modernizing industry and infrastructure,” Ben Sampson, Standard Investments managing director, said in a statement. In connection with the investment, Sampson is joining Albedo’s board of directors.

New and existing investors

New Albedo investors include Booz Allen Ventures, Cubit Capital and Bill Perkins. Existing investors contributing to the round include Breakthrough Energy Ventures, Shield Capital, Initialized Capital, Y Combinator, Giant Step Capital and Republic Capital.

Albedo is one of five commercial startups working with the National Reconnaissance Office. Under an agreement announced in December, the NRO will examine Albedo’s technical, business and cybersecurity plans. Once Albedo begins collecting space data, the NRO will evaluate its data products.

In preparation for launching its first satellite in 2025, Albedo expanded its staff. The company also established a facility in Broomfield, Colorado, large enough to build three or four satellites simultaneously.

Albedo has won two Small Business Innovation Research contracts valued at a $1.25 million apiece.

Alarming New Satellite Can Spy on Individual People: 

futurism.com

Maggie Harrison Dupré

"We should definitely be worried."

As surveillance tools advance in both function and ubiquity, an up-and-coming satellite venture company raises an important question: how much of our privacy are we willing to trade for the promise of safety?

A startup called Albedo Space https://albedo.com/ is building low-orbit satellites that are able to zoom in on individual humans down on Earth, The New York Times reports. The venture's cofounders say the satellites won't be equipped with identification-ready facial recognition technology, but they will be able to image people — a massive step forward in satellite-abetted surveillance that could seemingly realize some long-held privacy fears. After all, as far as technological Eyes of Saurons could go, a fleet of all-seeing orbital cameras — which according to the NYT have already inked multiple US defense contracts and garnered over $100 million in funding — feels pretty on the nose.

"This is a giant camera in the sky for any government to use at any time without our knowledge," Jennifer Lynch, general counsel of the Electronic Frontier Foundation, told the NYT. "We should definitely be worried."

Weighing Costs

As the NYT notes, Albedo's founders have paid lip service to the privacy concerns for some time now. In a February 2021 post to the forum Hacker News, for instance, Albedo co-founder and CEO Topher Haddad told a concerned netizen that "we are acutely aware of the privacy implications and potential for abuse/misuse."

This seems to be the company line, given that Haddad told the NYT for its 2024 report that "we're acutely aware of the privacy implications." So, acute awareness: check!

Speaking to the NYT, Albedo seemingly took the "but we're saving lives!" line of reasoning, emphasizing that its satellites — which are due to orbit as low as 100 miles off Earth's surface — could be used for purposes like helping authorities map disaster zones. Albedo's website also lists infrastructure monitoring and urban planning as possible applications for the tech, in addition — of course — to a few "defense [and] intelligence" use cases.

While some experts, according to the NYT, agree that the satellites could feasibly be helpful in some scenarios, the privacy concerns are palpable nonetheless. The thought of a tool like this in the hands of a government keen on moral policing, for example, or authorities seeking to crack down on protests, is frightening.

In spite of any benefits, surveillance technology almost always comes at a cost. Per the NYT, Albedo plans to launch its first satellite in 2025, and ultimately hopes to host a fleet of over 20 individual crafts. If and when Albedo's vision comes to pass, the public may well find out just how high its price is.

"It's taking us one step closer," Harvard astrophysicist Jonathan McDowell told the NYT, "to a Big-Brother-is-watching kind of world."

Meet Evologics, the German company developing submarine drones that network using sound







Meet EvoLogics, developing sub drones that pass data with sound - Defense One

EvoLogics GmbH is a private high-tech enterprise with headquarters in Berlin, Germany. The company designs and manufactures underwater information and communication systems, as well as hydroacoustic sensors. Its core values are rooted in bionic concepts that combine state of the art engineering with the best ideas found in nature.

EvoLogics was launched in 2000 with a small group of scientists and R&D experts, aiming to develop innovative technologies for maritime and offshore industries. To solve the common problems of transmitting data underwater, the team turned to dolphins - the ocean’s ’talking nation’ - known to use a wide variety of acoustic signals to efficiently communicate in the most challenging underwater conditions. The resulting EvoLogics S2C spread-spectrum communication technology grew into a whole ‘ecosystem’ of products that now includes several series of underwater acoustic modems, underwater positioning systems (USBL, LBL, SBL), networking protocols and developer frameworks, as well as novel robotic solutions.

SAN DIEGO—A flash of fiery reddish orange caught my eye as I was speed-walking through WEST 2024, the Navy’s annual IT conference: what looked like a cute little drone boat a tad bigger than a toddler’s walker, and some matching red-orange baubles.

Francisco Bustamante, EvoLogics’ director of operations and sales, explained that it was a suite of tech, including a surface drone and nodes to build a WiFi network underwater. 

D1: This is a data network that uses audio?

BUSTAMANTE: We started working with different products for underwater data transmission. That was one of the key technologies that we developed because there was basically no solution. Wi-Fi doesn't work. You can use optical systems, but they are also limited to the turbidity. So for any long-range communication, you need acoustic systems. 

You can use this as a technology to enable the operation of unmanned underwater vehicles, or even for manned vehicles...to position them underwater, and to transmit data to the surface.

Now that we have these enabling technologies, we have moved to other concepts. We are developing autonomous vehicles for different survey applications. We started with a survey vehicle for the surface, which is a sonar boat. It can perform different missions depending on what payload sensors that it has. We have single-beam and multi-beam echo sounders for water depth. And we have front-looking sonar and sidescan sonar to do, basically, object detection. 

The object detection we have included technologies with AI. In order to automate, we work with pre-trained datasets. And then the vehicle can look specifically for certain types of objects, for example, in assisting a police force looking for missing persons in water bodies or for finding mines in shallow waters, coastal areas, and so on.

So you’ve developed a surface vehicle and underwater connectivity. Next, is an unmanned underwater vehicle this year?

Yes, this vehicle can also carry different payloads and support survey missions. But the advantage being that it can also navigate closer to the floor, seafloor. And also it can obtain better resolution of the images or even, with support of the cameras, can go and look at some specific items that have been found. The important thing is that you always have a limitation in terms of communication underwater, even with our technology—and any technology basically—you have limited bandwidth. So you cannot be sending video and streaming on YouTube.

What kind of data can you send?

Text messages or text files. We can even send images like pictures, but single frames. So in that case, it's important that the systems—and this is something we have focused a lot on—that the systems can work autonomously and have enough intelligence [so] if the vehicle detects obstacles, that it's capable of avoiding them, if the vehicle detects objects of interest that it will communicate that information in a reduced way in terms of data size, but still giving the operator the opportunity to maybe change the mission and return to that point to have a closer look. 

Any detection that is made by the vehicle is already geotagged. So any further inspection—for example, sending a diver—can be much more easy, easily done, than if there was only a detection without knowing where it was.

What is the range of the surface vehicle, the underwater vehicle, and the underwater communication network?

The surface vehicle can travel up to 40 kilometers (about 25 miles) on one battery load. Normally, it's not going to travel that distance linearly. It searches [in] a grid pattern, so it covers a certain area. But that's basically the linear distance it can travel. 

This vehicle can also do about the same distance: about 40 kilometers underwater. This vehicle is relatively small, so it's about one-meter-10 [centimeters] or so, so it's very, very compact. And the idea is that you can easily deploy it. But on the other hand, we have the capability, thanks to the communication and the positioning, to operate multiple vehicles at the same time in coordination, so that you can act as swarms and cover a larger area in less time.

We have prepared a toolset that allows us to configure different solutions depending on the customer needs. For example, for port security, we can have different surface vehicles, underwater vehicles, sensor stations, that can then as a whole, create a detection network that can be used to prevent, for example, any kind of foreign vehicle that is in the area, or divers and so on, this can be configured in flexible ways depending on the requirements.

So the network that goes along with it covers that whole 25 miles?

The acoustic devices will have different ranges, depending on the frequencies that we're using. The longest range is up to seven miles, so 10 kilometers, with the lowest-frequency devices.  Medium range is 3.5 kilometers. And then we have high-frequency devices that can do up to one kilometer. But they can work, also, in network configuration. You can place multiple nodes in a larger area and they can communicate among themselves, transmit the data doing relay chains, or mesh networks in order to get the relevant information to the surface.

Is there open architecture so a customer like the U.S. Coast Guard could use systems they already have?

We have implemented the JANUS acoustic standards, which was developed by NATO, the CMRE Center for Maritime Research and Experimentation. And this has already been implemented in our modems. So it's a feature that we can deliver out commercially. We also are participants in the SWiG—Subsea Wireless Group—acoustic standard. They are part of the oil and gas industry...they have already developed a standard based on JANUS, but they are working on the next-generation standards to increase the bandwidth available and so on. So these standards will also be supported by our modem so that we can interact with any other modems that support basically the two available standards at the moment. Moving forward we will always be supporting the standards. 

In terms of open architecture, we have some interesting developer options built into our devices. We have a sandbox, this provides a virtual environment to the user, which allows them to run their own applications in our system. With this, they also get lower-level access to some of the modem features including the medium access control and can be used for testing networking features, and networking protocols. 

We also have a SDM—software-defined modem—which allows the users to basically play with any arbitrary waveform. If another company has some waveforms that they use for their own communication purposes, and they prefer to use that, they can use our modem as hardware.

Are you working with the U.S. military yet?

We have sold some products—in particular the modems so far; they are developing some projects. So hopefully we'll hear from them soon if their experimentation is successful.

What are your plans for the rest of this year?

Very important is the launch of the quatrain autonomous vehicle with the first project pilot customers, where we will be testing the capabilities basically to the limit. 

We are participating in the REPMUS exercise in Portugal in September with NATO to test different scenarios with them, in which we will also be testing and presenting the interoperability of all the components into one combined and comprehensive system that is also able to provide the data in the formats that is needed for the mission control by NATO. So this will be happening in September, and we hope that it will be very successful and will lead to new ideas and further development projects for us.

CNO Franchetti: Navy Exploring Robotics Rating as Unmanned Systems Expand

Chief of Naval Operations Adm. Lisa Franchetti speaks at the AFCEA International and U.S. Naval Institute West 2024 conference in San Diego, Calif., Feb. 13, 2024.

Summary of Keynote Address

Addressing Global Security Demands through Advanced Capabilities and Partnerships

The 34th annual collaboration between the U.S. Naval Institute and AFCEA International focuses on acquisition and readiness to meet global security demands. Notable challenges include conflicts in Russia, Ukraine, the Gaza Strip, Iran's activity in the Middle East, and tensions between China and Taiwan. Admiral Lisa Franchetti, the 33rd Chief of Naval Operations, emphasizes the importance of harnessing technology, adapting to new challenges, and working together to maintain the Navy's position as the world's most powerful navy.

Redefining conflict through technological breakthroughs:

The Navy recognizes the urgency to integrate and adopt new technologies, such as artificial intelligence, unmanned platforms, directed energy, and hypersonic missiles, that are redefining conflict and reshaping warfare. To draw parallels from history, the Navy reflects on the 1930s and 1970s – decades of challenging security environments and a changing character of war – to strategize and navigate the current dynamic landscape. In the 1930s, leaders shifted from a platform-centric strategy to an integrated naval force, while in the 1970s, they recognized the need for new capabilities to contest sea control globally. 

In response, the Navy is taking a similar approach today by viewing everything through a warfighting lens, investing in disruptive systems, exploring manned-unmanned teaming, bolstering fleetwide connectivity, and emphasizing the importance of people as the true strategic advantage. This urgent call to action requires unity of effort, a strong sense of resolve, and the integration of disruptive and emerging technologies to ensure the Navy remains the world's preeminent naval force.

Improving Sailors' Living and Working Conditions:

Admiral Franchetti highlights a priority for the navy the importance of addressing sailors' living and working conditions as a key initiative. This includes improving barracks with new furnishings, free Wi-Fi, and better cooking facilities, as well as addressing issues with parking and access to medical and mental health care. The overall goal is to provide a better quality of life for sailors, enabling them to recharge and focus on their work. 

Additionally, the Navy is working on hiring more mental health providers, setting up wellness centers, and encouraging leaders to connect with their teams to understand and address their needs. In the context of the Navy's broader goals, Admiral Franchetti emphasizes the importance of a hybrid manned-unmanned Fleet and sets a realistic timeline for its implementation. This includes prototyping, experimentation, procurement, and operation of unmanned platforms, as well as the development of necessary infrastructure and networks. 

The Navy is also focusing on partnering with allies and partners to advance unmanned technology. Admiral Franchetti acknowledges the challenges in recruiting and retention, emphasizing the need to retain high-quality sailors and address "sea blindness" by communicating the Navy's mission and value effectively. Lastly, Admiral Franchetti explains how NAV's mission and ship maintenance support the foundation pillar in the America's War Fighting Navy priorities, specifically by establishing guidelines for shipyard maintenance that will help ensure platforms are serviced efficiently and effectively.

SAN DIEGO – A new robotics rating is likely coming to the Navy, the sea service’s top leader said on Tuesday.

The Navy is exploring the option of a robotics rating in order to build a team that would be responsible for the Navy’s unmanned platforms, Adm. Lisa Franchetti said during her keynote speech at the West 2024 conference, cohosted by AFCEA and the U.S. Naval Institute.

The sea service wants “a team who has the reps and sets in sensors, platform autonomy, and mission autonomy programs … and can provide input in machine learning feedback processes,” Franchetti said in her speech.

Although Franchetti previewed the forthcoming rating, little information is available about what the rating will look like.

A spokesperson with the Office of the Chief of Naval Personnel said that the Navy is still exploring the rating and nothing is yet official.

It is unclear where the robotics rating will fall. The Navy’s unmanned program is under Naval Air Systems Command.

The possibility of a robotics rating comes as the Pentagon writ-large is planning to expand its stable of unmanned systems in the near term.

A prime focus of the Defense Department in the near term is the Replicator initiative, the creation of a swarm of unmanned vehicles to solve specific battle problems the U.S. faces over the next few years. The first major challenge will be to disrupt the amphibious invasion of Taiwan by China using a combination of lethal unmanned surface and aerial vehicles.

In the longer term, the Navy is set to field a fleet of medium and large unmanned surface vehicles that will add sensors and magazine capacity of the fleet. The service is also expanding its unmanned aerial portfolio to include the MQ-25A Stingray refueling tanker, which will be the first unmanned aircraft to operate from a U.S. aircraft carrier.

The Navy is also working with robotic systems as part of its emerging mine countermeasures systems both expeditonary and part of its Littoral Combat Ship.

Franchetti said the new rating could be part of the future manned and unmanned teaming for the future fleet using examples of the unmanned systems tests with systems in U.S. 5th Fleet in the Middle East and U.S. 4th Fleet in the Caribbean.

“Unmanned systems have enormous potential to multiply our combat power by complementing our existing fleet of ships, submarines, and aircraft through manned-unmanned teaming,” she said.
“Especially in areas like maritime surveillance and reconnaissance, mine countermeasure operations, seabed exploration and carrier air wing support.”

 

Illuminating the Future: The Rising Role of Laser Free Space Optical Communication (FSO) – International Defense Security & Technology

NASA's Optical Communications Program: A Breakthrough in High Broadband Technology

NASA's optical communications program, led by Don Cornwall, has experienced significant advancements in the last few years. After decades of attempts and cancellations in free-space optical communications programs, NASA has finally surpassed the threshold, enabling the development of viable laser systems for operations. The primary driver for this shift is the need for higher bandwidth to accommodate the increasing data from space instruments. For instance, transmitting a 30-centimeter resolution Google map of the Martian surface at one bit per pixel using the best RF system would take nine years. However, with optical communications, the same task could be accomplished in just nine weeks. 


The Lunar Laser Communications Demonstration (LLCD) mission, led by MIT Lincoln Laboratory and NASA, was a significant milestone. The Lunar Atmosphere and Dust Environment Explorer (LADEE) spacecraft, approximately a meter and a half tall and a meter in diameter, was used for this mission. In October 2013, LADEE established a laser link back to a ground station on Earth, setting download and upload speed records of 600 megabits per second and 20 megabits per second, respectively. This high-performance laser communication system, operating at a distance of 400,000 kilometers, is comparable to streaming 30 HDTV channels. Despite the considerable improvement, optical communications have a major challenge: narrow beams. The six-kilometer beam from the moon to Earth requires precise pointing, which is difficult to achieve over such great distances. The LADEE spacecraft utilized an innovative system that measured micro-vibrations and compensated for them, ensuring the beam remained on target. This breakthrough technology is crucial for demonstrating the viability of optical communications as a practical technology for space exploration.

NASA, along with international partners, is making significant strides in deep-space and near-Earth optical communications. The Lunar Laser Communication Demonstration (LLCD) marked a successful optical communication mission to the moon, influencing naysayers at NASA to pursue further advancements. 

NASA's advancements in deep-space and near-Earth optical communications 

The next step is the Deep-Space Optical Communications project, aiming to build a terminal for Mars with anticipated data rates of 250 megabits per second. This project requires more powerful laser transmitters and advanced disturbance isolation systems due to the greater range loss. 

In the realm of near-Earth optical communications, NASA demonstrated 50 megabits per second from low-Earth orbit with the OPALS mission, while the Optical Communication and Sensor Demonstration (OCS D) CubeSat mission launched to low-Earth-orbit in early December 2017, the OCSD mission is addressing two cross-cutting capabilities of value to many future small spacecraft missions: high-speed optical transmission of data and small spacecraft proximity operations. The OCSD project is developing and leveraging technologies that consist of a low power laser communication system, proximity sensors, and a compact water- based propulsion system to enable the demonstration of technology firsts in these two areas.

Additionally, NASA's Laser Communications Relay Demonstration, a geostationary satellite relay mission, payload is hosted aboard the U.S. Department of Defense’s Space Test Program Satellite 6 (STPSat-6). After launch Dec. 7, 2021, engineers at LCRD’s mission operations center in Las Cruces, New Mexico, turned the payload on and prepared it to start transmitting data over infrared lasers. Until its first user is launched, LCRD will practice sending test data to and from its ground stations. This test data will be sent up through radio frequency signals from the mission operations center and then the LCRD spacecraft will reply over optical signals. This test data will include spacecraft health data; tracking, telemetry, and command data; and sample user data to ensure LCRD is properly operating.

Introduction

In an era where data reigns supreme and connectivity is vital, innovative technologies are reshaping how we communicate, especially beyond our planet’s boundaries. Laser Free Space Optical (FSO) communication, a transformative method of transmitting data using laser light, is rapidly emerging as a game-changer for a multitude of applications. From lunar missions to remote areas on Earth, FSO technology is revolutionizing communication in ways we could only dream of. In this article, we’ll delve into the growing importance and diverse applications of FSO technology.

Optical Wireless Communications (OWC), or Free-Space Optical Communication (FSO)

Broadband Internet access, providing high-speed connectivity with a minimum data transfer rate of 256 Kbit/s, remains unavailable in numerous regions, presenting a significant challenge in today’s world. In areas like densely populated urban environments, where the installation of optical fiber infrastructure incurs substantial costs, wireless Internet access has become increasingly popular.

While microwave-based data transfer technology has advantages such as direct transmission through space without signal bending and the ability to bypass the ionosphere, maintaining microwave links in large cities has grown challenging due to radio frequency saturation, susceptibility to interference, and data security concerns. High license fees for frequency bands and worries about potential health effects have also limited their widespread use.

To address the growing demand for faster and more efficient data transfer while mitigating these limitations, Optical Wireless Communications (OWC), also known as Free-Space Optical Communication (FSO), has emerged as a promising alternative. FSO is a wireless optical communication technology that utilizes open space to transmit data between two points without obstructing the line of sight.

Unlike optical fiber communication, FSO operates through an unguided channel, such as the atmosphere or vacuum in space. This technology harnesses visible and infrared light for data transmission, offering advantages such as high bandwidth, rapid deployment, low power consumption, and cost-effective transmission. It is particularly valuable in scenarios where laying optical fiber is impractical or unfeasible. Nonetheless, FSO links are sensitive to atmospheric conditions, such as snow, fog, and rain, which can scatter and absorb signals, leading to attenuation and limiting their range and capacity. Despite these challenges, FSO technology has matured, with successful demonstrations and operational applications, including SILEX, GOLD, LADEE, and the European Data Relay System (EDRS), marking a new era in laser-based communication.

Free-space optical communication (FSO) is a method of transmitting optical signals from one location to another through the Earth’s atmosphere or the vacuum of space. FSO relies on the Line-of-Sight principle, requiring an unobstructed path between the transmitter and receiver for effective communication.

In FSO, data transmission occurs via a wireless medium using modulated near-infrared light beams, typically with wavelengths between 800 nm and 1700 nm, as the carrier wave. At the transmitter, input data is converted into a modulated electrical signal that controls the intensity of the laser light by manipulating the laser current. The transmitter’s telescope focuses this modulated laser beam towards the receiver’s telescope. The optical signal travels through the medium and is received by the receiver’s telescope. A photodetector at the receiver then converts the optical signal back into an electrical signal, which is subsequently demodulated to retrieve the transmitted data. To eliminate background solar radiation, an optical filter is employed at the receiver.

FSO links are straightforward in construction, typically consisting of two identical heads that enable duplex data transmission. These heads are directly connected to computers or telecommunications networks. The optical radiation source can vary, including light-emitting diodes (LEDs), semiconductor lasers, or vertical-cavity surface-emitting lasers (VCSELs). LEDs and semiconductor lasers are suitable for short-distance wireless optical links, such as indoor applications, while VCSELs are preferred for longer-distance FSO links due to their increased power and faster transmission speeds. Lasers, with their coherent light beams, high-frequency modulation capabilities, and low beam divergence, are the preferred light sources for advanced FSO applications.

FSO technology can be categorized into four main sub-types: terrestrial, non-terrestrial (or aerial), space, and deep-space. Terrestrial FSO links are used for communication between buildings. Non-terrestrial FSO links encompass connections between the ground and unmanned aerial vehicles (UAVs), ground-to-high altitude platform systems (HAPSs), and HAPS-to-HAPS links. Space FSO includes ground-to-satellite, satellite-to-ground, and satellite-to-satellite links, with the latter often referred to as laser inter-satellite links (ISLs). Finally, deep-space FSO involves communication between Earth and spacecraft in deep space, such as the Galileo mission.

Challenges of FSO technology

There are a few challenges that need to be addressed before FSO technology can be widely used for interplanetary communication:

  • Atmospheric conditions: FSO communication can be affected by atmospheric conditions, such as clouds and fog. Researchers are developing new techniques to mitigate the effects of atmospheric conditions on FSO communication.
  • Pointing and tracking: FSO communication requires precise pointing and tracking of the transmitter and receiver. Researchers are developing new pointing and tracking technologies for FSO communication.
  • Cost: FSO communication systems can be expensive to develop and deploy. Researchers are working to reduce the cost of FSO communication systems.

Researchers are developing a number of techniques to mitigate the effects of atmospheric conditions on FSO communication, including:

  • Adaptive optics: Adaptive optics systems can be used to compensate for atmospheric turbulence, which can degrade the quality of FSO signals. Adaptive optics systems use deformable mirrors to correct for the distortions caused by atmospheric turbulence.
  • Diversity techniques: Diversity techniques involve using multiple FSO links to transmit the same data. This can help to improve the reliability of FSO communication by reducing the effects of atmospheric conditions. For example, if one FSO link is affected by fog, the other links may still be able to transmit data successfully.
  • Coding techniques: Coding techniques can be used to reduce the errors caused by atmospheric conditions. Coding techniques involve adding redundancy to the transmitted data so that the receiver can correct for errors.

In addition to these techniques, researchers are also developing new FSO system designs that are more resistant to atmospheric conditions. For example, researchers are developing FSO systems that use shorter wavelengths of light, which are less affected by atmospheric conditions.
