  Air Force gets new stopgap system for GPS 3 satellites

  By: Nathan Strout The U.S. Air Force's first next-generation GPS satellite launched in December and the second GPS III satellite is slated to liftoff in July. But there Air Force has a problem: The ground system currently in use isn't fully capable of controlling GPS III satellites. Worse, a new ground system that can, formally known as the next-generation operational control system (OCX), is five years behind schedule and won't be delivered until June 2021 at the earliest, according to the Government Accountability Office. Enter the GPS III Contingency Operations (COps) software—a critical stop gap measure that will update the current ground control system and allow it to access some of the more advanced features of the GPS III satellites until the next-generation operational control system is ready. On July 11, primary contractor Lockheed Martin announced that it had delivered the COps upgrade to the Air Force. “Positioning, navigation and timing is a critical mission for our nation and COps will allow the Air Force to gain early access to its new GPS III satellites,” said Johnathon Caldwell, Lockheed Martin's vice president for Navigation Systems. “We just finished final qualification testing and delivery on COps, and it will be integrated and installed on the [Architecture Evolution Plan Operational Control System] over the summer. We look forward to the Air Force ‘flying' a GPS constellation on the COps OCS which includes the new GPS III satellites, later this year.” The new GPS III satellites are built to be more robust and accurate than their predecessors and come with advanced features such as the ability to use M-Code, an encrypted GPS signal for use by the military. The COps upgrade will allow the current ground system to control the GPS III satellites as well as the legacy GPS satellites. It will also allow the current system to access M-code Early Use, an encrypted GPS signal with improved anti-jamming and anti-spoofing capabilities, beginning in 2020. The Air Force contracted with Lockheed Martin to deliver the patch in 2016, the same year that the OCX program triggered a Nunn-McCurdy cost breach—a type of violation caused by significant cost growth that requires a program to be shut down unless the Department of Defense intervenes and approves a new cost estimate. The $6.2 billion OCX program is already five years behind schedule, and a May 21 Government Accountability Office report warned that the OCX program could be delayed even further. In addition, the Air Force has acknowledged that delays are possible during the seven-month testing period following delivery. Raytheon, the primary contractor behind OCX, rejected the GAO report, claiming that its findings were inaccurate. https://www.c4isrnet.com/battlefield-tech/c2-comms/2019/06/11/air-force-gets-new-stopgap-system-for-gps-3-satellites/

  US Air Force explores space-based cargo operations, confirms talks with SpaceX

  By: Jeff Martin GRAPEVINE, Texas — The U.S. Air Force is exploring the logistics of space-based cargo operations under the purview of Air Mobility Command, even as the impact of a new Space Force on the mobility community remains to be seen. “I don't know how it will affect mobility, but most of you know space affects mobility every day,” Gen. Paul Selva, vice chairman of the Joint Chiefs of Staff, said Thursday at the 2018 Airlift/Tanker Symposium outside Dallas, Texas. “Whatever the Space Force is or does, it has to protect our national interest in space,” he said, adding that GPS is critical to the air mobility community. As for what space cargo operations could look like, the previous head of Air Mobility Command, Gen. Carlton Everhart, espoused the possibility of moving cargo using rocketsduring a Defense Writers Group breakfast in August. “Think about this. Thirty minutes, 150 metric tons [and] less than the cost of a C-5,” he said at the time. Apart from cargo operations, such a focuses space presence could help with pre-positioning equipment and supplies in orbit, ready to be dropped to Earth. But in a roundtable with reporters Friday, the new commander of AMC, Gen. Maryanne Miller, said while the command continues to study the possibility, space cargo operations remain at the conceptual stage. “We're continuing, our [planning] community is going to continue to have discussions with the space companies, and we have agreed to just sit with them and just stay up to date with where they're going with their future plans, to just be at the table with them” she said. “We won't commit any resources, but we've committed to work with them to see how quickly they progress through that." One potential would be SpaceX's next-generation reusable BFR rocket, currently under development. During the roundtable, Miller confirmed that the Air Force had spoken to SpaceX about the idea. “They have talked about moving cargo in space, and we've sat down with SpaceX and had that discussion. But it's really just discussion at this point," she said. “Our connection with space is really just going to be at the table with them, to look at how much progress they're making.” As for what type of cargo could possibly be moved, that's still being discussed. But in August, Everhart said he'd be willing to stick “anything” in space. https://www.defensenews.com/digital-show-dailies/airlift-tanker-annual/2018/10/26/us-air-force-explores-space-based-cargo-operations-confirms-talks-with-spacex
