    Pentagon Seeks New SatCom Tech For ‘Fully Networked C3’

    "Our fully networked C3 [Command, Control, & Communications] will look completely different" from current satellites and terminals, said OSD's Doug Schroeder. By THERESA HITCHENS SATELLITE 2020: The Pentagon wants industry ideas on how to craft a “fundamentally new architecture” for command, control and communications (C3) that will allow “any user using any terminal to connect to any other user using any other terminal,” says Doug Schroeder, who oversees the effort under the Office of Research and Engineering (R&E). This kind of omnipresent, all-service connectivity across land, sea, air, and space is essential for the Pentagon's rapidly evolving of future war, known as Joint-All Domain Operations. “Our Fully Networked C3 communications will look completely different. We have a new vision. We're crafting it with the help of industry,” he said. “We're relying on very heavily on industry, starting with this Broad Agency Announcement dated March 6,” which asks for companies to submit white papers in short order. According to Schroeder, the Space Development Agency (SDA) will be the funding authority. Vendors whose short, 10 to 15 page white papers are chosen will be invited at the end of April to a Pitch Day. Winners then will be given three months to develop a proposal; contracts for prototypes will be granted 24 months later. Speaking to a relatively sparse audience here at the annual commercial satellite industry conference, Satellite 2020 — which is underway despite the threat of the COVID-19 Coronavirus — Schroeder stressed: “We are going to take our new direction from you.” The new strategy, called Fully Networked C3 (FNC3), is being spearheaded by R&E director Mike Griffin and his assistant director for FNC3, Michael Zatman. According to the BAA, the first issued under the effort, the new strategy is being designed to “enable the DoD to reliably communicate with all its tactical and strategic assets.” C3 is one of Griffin's Top Ten areas of technology innovation for which DoD is developing an agency-wide development strategy. Specifically, DoD now is looking for “Beyond-Line-Of-Site (BLOS) communications systems for airborne, surface, and subsurface systems that is [sic] compatible with both FNC3 enabled systems and legacy systems,” the BAA states. The BAA calls for White Papers to be submitted by March 30 for three different types of BLOS technologies: 1. Protected Radio Frequency (RF) BLOS Communications. 2. Multi-User/Multi-Point High-Data-Rate Laser Communications. 3. Communications with submerged assets. R&E intends to “develop, prototype, and demonstrate each innovative communications capability with the goal of transitioning the technologies into programs of record,” the BAA said. To ensure speedy results, DoD will use Other Transaction Authority (OTA) for prototyping (found under 10 U.S. Code § 2371b.) Much of the detail about the effort is contained in classified annexes. What we do know: Beyond-Line-Of-Sight communications relayed through satellites generally require equipping platforms — such as aircraft, ships, and ground vehicles — with high-throughput voice and data links, capabilities all of the services have expressed interest in. In particular, after years of little progress, Griffin has reinvigorated DoD interest in optical communications via laser links, in large part due to fears about Russian and Chinese RF jamming. Commercial industry has been rushing to develop optical links to enable satellite-to-satellite data transmission, and the Space Development Agency is interested in that capability for its so-called transport layer of small satellites in Low Earth Orbit. Radio-frequency communications with submarines when underwater are generally limited to terse text messages, transmitted at very low frequencies (three to 30 kilohertz) and extremely low frequencies (three to 300 hertz) and requiring very large antennas to receie them. Research work is ongoing at MIT on how to link traditional underwater sonar to airborne RF receivers, a methodology called Translational Acoustic-RF) communication. Research also is ongoing, including at MIT's Lincoln Lab, on using narrow-beam lasers to allow one underwater vehicle to communicate with another. BLOS communications can also be accomplished without using satellites. Alternative method include tropospheric scatter using microwave radiation, high frequency (HF) wireless, unmanned aerial vehicle (UAV) relays, and passive reflector systems. https://breakingdefense.com/2020/03/pentagon-seeks-new-satcom-tech-for-fully-networked-c3

    Britain moves to protect its defense industry from foreign influence

    By: Andrew Chuter LONDON – Defense and space industries are among nearly twenty sectors named by the British government in the introduction of new legislation Nov. 11 aimed at tightening regulations allowing it to block potentially hostile direct foreign investment. The government said the National Security and Investment Bill will strengthen its ability to investigate and intervene in mergers, acquisitions and other types of deals potentially posing a threat to British national security. Artificial intelligence, robotics, military or dual-use technologies, satellite and space technologies, defense and critical suppliers to the government were among 17 industry sectors included in the new legislation. The new powers allow the government to act against investors from any country, including the United States. “Under the National Security and Investment Bill, the government will be taking a targeted, proportionate approach to ensure it can scrutinize, impose conditions on or, as a last resort, block a deal in any sector where there is an unacceptable risk to national security,” said the Department for Business, Energy and Industrial strategy in a statement. The acquisition of sensitive assets and intellectual property, as well as the acquisition of companies is covered by the legislation. The government said the move brings British legislation into the 21st century. Reporting of deals in the sectors covered by the legislation will be mandatory and companies could face heavy fines and the transactions made void if they fail to get approval from the Business department. Britain's effort to shut the door on unwelcome investors like the Chinese is part of a growing trend among Western nations. Earlier this year the United States introduced mandatory notification requirements for transactions concerning specified types of businesses as part of a broader program of reform. The Australian government have also introduced legislation requiring foreign investors to seek approval to acquire a direct interest in sensitive national security businesses. The powers pending before parliament are similar to those already in place with allies like France, Germany and Italy, said the government. Paul Everitt , the chief executive of the defense, aerospace and security lobby group ADS, welcomed the move but said it was important the government didn't deter overseas investors. “The government's plans must strike an appropriate balance between putting protections in place and continuing to ensure the UK remains an attractive environment for international investment,” said Everitt. Consultant Howard Wheeldon, of Wheeldon Strategic Advisory, also supported the government action, but he cautioned: “Does it [the legislation] have sufficient teeth? We certainly need to protect our specialist industry but we must also ensure and expect the playing field to be kept level.” https://www.defensenews.com/global/europe/2020/11/12/britain-moves-to-protect-its-defense-industry-from-foreign-influence/

  • Support growing for review of Ligado interference information

    Support growing for review of Ligado interference information

    Aaron Mehta As the Department of Defense and its allies attempt to stop Ligado from moving forward with plans the Pentagon says will harm the Global Positioning System, consensus is growing around the idea of an independent review of the testing the Department had completed for interference. The dispute stems from the Federal Communications Commission's decision to approve Ligado's request to use L-Band spectrum, first reported by C4ISRNET April 10. Now the question is whether Pentagon tests showing that Ligado's plan would interfere with GPS signals vital to military, commercial and civilian technologies are still relevant, given mitigation plans from the company. A May 6 Senate Armed Services Committee hearing on the issue underlined a fundamental disconnect between the two sides over technical testing of Ligado's capabilities, a he-said-he-said situation where both sides claim the data shows the other is comprehensively wrong. That disconnect is an issue for Sen. Jim Inhofe, R-Okla., the chairman of the SASC and a vocal supporter of the Pentagon's position. “What I took away from our hearing last week was that the results of DoD's testing just don't match up with the testing the FCC relied on to make their decision; in fact, I'm concerned they were looking at different things,” Inhofe told C4ISRNET this week. “It seems to me the FCC didn't really give DOD's analysis — which was done in conjunction with eight other federal departments — fair consideration,” Inhofe continued. “While I trust the Pentagon's conclusions, I think we'll all sleep better at night if we have more independent testing done to verify just how Ligado's plan will affect our GPS signals.” While not saying who should do the verification, Inhofe's comments match up with calls from a trio of non-defense trade groups that in the last few days have specifically called for the National Academy of Sciences — a non-profit, non-governmental research institute that can play a role as a neutral arbiter — to take a fresh look at the data gathered by both the Pentagon and Ligado and weigh in. On May 8, Securing America's Future Energy and the Intelligent Transportation Society of America tweeted that NAS should specifically lead a new round of testing, while Dana Goward, president of the non-profit Resilient Navigation and Timing Foundation, also supported the idea in a May 11 op-ed for C4ISRNET. “Congress must select a technically competent and impartial entity such as the National Academy of Sciences to fill this role. This entity must review the work that has been done and conduct any further analysis needed to inform policy makers,” Goward wrote. “The technologies involved are mature. Testing methodologies are well established. This will not be an onerous task.” Pausing the FCC's decision while launching a review of the testing data would likely require approval from the Commerce committees. House Energy and Commerce Committee ranking member Rep. Greg Walden, R-Ore., suggested further work would be redundant. “We must ensure that this decision maintains our national and economic security, which is why this technology was tested, modified, and tested again, several times before the FCC reached its decision,” Walden said in a statement to C4ISRNET. The Pentagon, thus far, has been reluctant to agree to further technical testing, with Dana Deasy, the department's Chief Information Officers, shooting down the idea in a May 6 call with reporters. However, Defense leaders are now open to an independent review of existing test data, according to Lt. Col. Robert Carver, a department spokesman. He said in a statement the Pentagon would “support an impartial third party, one with demonstrated expertise in GPS testing, conducting a thorough examination of all data collected during the preceding decade of testing. “We emphasize any such examination must be conducted by a party with unquestioned capability, capacity and experience in this arena. We believe a painstaking examination of existing test data will confirm the results of all previous tests, including the limited tests funded by Ligado, that Ligado's proposal will result in interference to GPS even at the one-decibel level,” Carver said. “Any testing, or evaluation of prior testing, must address protection of the GPS service, the frequency band assigned to it, and all receivers intending to use that service." A Ligado spokesperson declined to comment. In the meantime, the department continues to push through the formal process to request the FCC change its mind. That would be a tough path forward for any vote that passed unanimously with five votes, as it would require three members of the commission to change their mind. It may be even more difficult given the comments from Deasy, Inhofe and others indicating the FCC purposefully kept DoD out of the loop as it was making its decision. In a statement after the hearing, an FCC spokesman blasted “all of the untrue statements” made by officials, called claims of unanimous opposition in the government “blatantly false,” and saying assertions that DoD was blindsided are “preposterous.” “The bottom line here is that the FCC made a unanimous, bipartisan decision based on sound engineering principles,” the spokesman said. “We stand by that decision 100% and will not be dissuaded by baseless fearmongering."
