  DoD Pushes To Reverse FCC OK Of Ligado 5G Network

  "The impact is significant, and it's unacceptable," Gen. Jay Raymond told the Senate Armed Services Committee. By THERESA HITCHENSon May 06, 2020 at 8:14 PM WASHINGTON: DoD is pressing for the FCC to reverse its controversial decision to approve Ligado's plan to create a mobile 5G communications network, one the Pentagon asserts will jam GPS receivers. “It is clear to DoD that the risk to GPS far outweighs the benefits of this FCC decision. And the FCC needs to reverse their decision,” DoD CIO Dana Deasy told the Senate Armed Services Committee (SASC) hearing during a marathon hearing this afternoon. A formal “re-petition” action has to be taken by National Telecommunications and Information Administration (NTIA) by the end of May. NTIA, which falls under the Commerce Department, coordinates federal agency use of the radio frequency spectrum. DoD, Deasy told the SASC, is working to provide NTIA with the necessary technical information to do so. SASC members were divided on the wisdom of the FCC's April 20 decision to approve Ligado's latest plan to repurpose its current L-band spectrum for use in a US-wide terrestrial 5G network. The SASC hearing did not fall along partisan lines. Instead, the division came between the SASC leadership and the committee's members who also sit on the Senate Commerce, Science and Transportation Committee. It has jurisdiction over the FCC. For example, while Republican SASC Chairman James Inhofe and Democratic Ranking Member Sen. Jack Reed excoriated the FCC decision, Republican Sen. Roger Wicker, who chairs the Commerce committee, expressed support for the FCC. Indeed, a number of senators with a foot in the Commerce Committee raised the fact that the FCC's decision not only was approved unanimously by the five FCC commissioners, but also has been praised by Secretary of State Mike Pompeo and Attorney General William Barr. (Barr was tapped by President Donald Trump on April 4 to head a new Telecom Team designed to ensure that China cannot dominate the 5G marketplace and undercut the security of emerging US networks.) DoD and many other agencies, including the Transportation Department, have opposed the planned Ligado (formerly LightSquared) network for nearly a decade, arguing that it will drown out GPS signals in most current receivers. Their protests have been echoed by a wide swathe of the defense and commercial transport industry, including the Aerospace Industries Association and the National Defense Industrial Association. Indeed, according to a press release put out today by Inhofe's office: “This opposition extends to the private sector as well. Numerous industries across the gamut – commercial air, satellite communications, weather, construction, and more – have also registered their objections to the FCC's Order.” Mike Griffin, head of DoD Research and Engineering, explained that the issue is the “noise” that will be created by Ligado because it will use spectrum designed for satellite use to rebroadcast via terrestrial cell towers. He said that the situation for the vast number of GPS receivers today would be analogous to trying to hear the “rustling of leaves” through the noise of “100 jets taking off all at once.” Perhaps most significantly, Griffin pushed back hard against Ligado's assertions in FCC filings (and most recently in a letter today to the SASC obtained by Breaking D) that most receivers would not be affected. He said testing done by the Transportation Department showed that high-end GPS receivers used in civil aviation, which costs some $10,000 each, are impacted by Ligado's planned signal strength. Even those “hardened” receivers are “barely capable” of discerning GPS signals through the “noise” caused by Ligado's 9.8 dBW — an energy level about equal to that put out by a 10 watt light bulb). More worryingly, Griffin asserted that most commercial GPS receivers — including those that would be used to guide self-driving cars in the future — “lose lock” on the signal at a power level some 100 times lower than Ligado plans to use. Gen. Jay Raymond, double hatted as the head of Space Force and Space Command, told the SASC that Ligado's network would have a “significant impact” on Dod's homeland defense mission, as well as on military and commercial space launch capabilities. “In my opinion, the impact is significant, and it's unacceptable,” he said. While Deasy said one avenue for reversing the decision could be legislative action, it remains unclear what the SASC can actually do, however — should the committee even be able to agree on a course of action. Inhofe said it is legally unclear to him right now whether the Congressional Review Act, that allows Congress to overturn a decision by a federal agency, actually applies to the FCC decision for technical reasons. (The FCC officially is independent of the Executive Branch.) Retired Adm. Thad Allen, former Coast Guard Commandant and chair of the Space-Based Positioning and Timing National Advisory Board, suggested that the Senate Commerce Committee should hold a hearing and force the FCC to reconsider. Those members of that committee participating today, including Wicker, seemed reluctant to consider the idea of even having an exploratory hearing. For example, Democratic Sen. Richard Blumenthal suggested that the matter perhaps might be better adjudicated in the courts, given the questions raised about the legalities of the FCC's administrative process that have been raised by members of Congress as well as several industry groups. https://breakingdefense.com/2020/05/dod-pushes-to-reverse-fcc-ok-of-ligado-5g-network/

  Need to upgrade Army vehicle software? Got 10 minutes?

  By: Adam Stone The Army is rolling out a new streamlined tool for updating critical software on thousands of vehicles that use the Joint Battle Command-Platform (JBC-P) system. Vehicles depend on the Force XXI Battle Command Brigade and Below system to deliver communications, friendly and hostile-force tracking, maps and other key intelligence, surveillance and reconnaissance functionality. But FBCB2 is out of date, and upgrades have required the pricey and time-consuming replacement of both hardware and software. “We wanted to give war fighters the option of doing a software-only upgrade,” said Dan Ghio, JBC-P deputy product manager. “We will still hit them with the full hardware upgrade eventually. This just gets us to a more common software baseline in the meantime. It's a stopgap for those who can get at least some of the upgrades done.” The upgrades started rolling out in the spring and so far over 800 vehicles have completed the process. Of the 103,000 fielded platforms, roughly 20,000 to 30,000 can be updated using the new approach, which applies to platforms such as Humvees and Mine-Resistant Ambushed-Protected vehicles. All upgrades should be completed by fiscal 2023, said Lt. Col. Shane Sims, JBC-P product manager. “We started with a unit at the National Training Center at Fort Irwin, California, just to see if we were on track,” Sims said. “The process is pretty easy. You call our help center and our folks will send out a new hard drive with the new software loaded on it. Once you attach it to the system it's a 10-minute process to load it up.” While it would have been technically possible to upload the software via the internet, connectivity constraints made the hard drive a better option. “These are users with very limited bandwidth. It would take a very long time to fully download a new operating system,” Sims said. By sending out new hard drives, the engineers also help to position the system for future enhancements, while reducing the overall burden of system support. “We want to keep pushing more and more capabilities out into the field, but right now our support teams in the field have to support 18 different hard drives. There is a huge sustainment cost to supporting all of that,” Sims said. “We're a huge Army and the more we standardize, the better it is.” The latest software version includes a few significant functional enhancements. The user interface has been modernized and made more intuitive; engineers have hardened the security on the back end and made the system more reliable, Ghio said. By creating a “standardized, repeatable and intuitive process” for upgrades, he said, Army aims to empower war fighters to take control over their most critical technologies. “We believe solders and commanders can take on some of the [technology] mission themselves if given the right tools and the right instructions,” Sims said. “As we move to the future, we are going to have to rely on our units to modernize things on their own. That will allow us to inject new capabilities at a much faster pace.” Looking ahead, Army engineers are still looking to overcome the bandwidth limitations that presently prohibit them from pushing out upgrades online. “We are definitely looking at ways to do an over-the-air update,” Sims said. “It would be a lot of easier, just the same way you do an update to an iPhone or an Android. We could send a message to the entire force and have everyone updated at once. That would improve our security posture and would serve to keep everyone current.” At the same time, safety and security concerns factor heavily, as the Army looks to enhance systems on vehicles that are equipped for live fire. “A software malfunction on a firing system would be a catastrophic event, so we have to make sure that our software doesn't interfere with any of the safety mechanisms on these platforms,” Sims said. https://www.c4isrnet.com/it-networks/2018/12/13/need-to-upgrade-army-vehicle-software-got-10-minutes
