  GPS III satellites are nearly ready to launch, but what’s being done on terra firma to support them?

  By: Daniel Cebul The U.S. Air Force is getting ready to deliver the first of its next-generation GPS III satellites into orbit later this year, and expects the new satellites to deliver significant capability improvements. But much work also needs to be done on Earth to make sure the Air Force is able to get the most out of the platforms. That's why Lockheed Martin will begin a series of updates to the architecture's ground control system following the initial launch, according to a statement from the company. These updates will give the Air Force get a head start on testing and operations before the majority of the constellation is in place. The Air Force placed Lockheed Martin on contract in 2016 and 2017 to upgrade the existing Architecture Evolution Plan (AEP) Operational Control System (OCS) called GPS III Contingency Operations (COps) and M-Code Early Use (MCEU), respectively. Just as the GPS III satellites themselves are equipped with improved anti-jamming technology and more accurate signals transmission capability, the ground systems and software that control them need to be upgraded as well. The Air Force has also worked with Raytheon on the estimated $6 billion Operational Control Segment program, often referred to as OCX. That program is expected to serve as the primary ground control system for the GPS III program but has been behind schedule. SpaceNews recently reported the target completion date for Block 1 of the program is June 2021. Block O, the launch and checkout system, was delivered in September 2017. ockheed Martin's contingency program will allow the existing control system to support and integrate more powerful GPS III satellites. Modifications will support GPS III satellites in their position, navigation and timing missions, coordinating their movement with GPS IIR, IIR-M and IIF satellites already in orbit. A second set of upgrades, known as the MCEU modernization program, will focus on the development of M-Code, a new advanced signal designed to improve anti-jamming and anti-spoofing capabilities. The program will improve the existing ground system and allow it to task, upload and monitor M-Code within the GPS constellation. In other words, MCEU modernization will help the Air Force integrate and test GPS III satellites into the current constellation earlier. COps is on schedule for delivery in May 2019 and MCEU is scheduled for delivery in January 2020. https://www.c4isrnet.com/c2-comms/satellites/2018/09/14/gps-iii-satellites-are-nearly-ready-to-launch-but-whats-being-done-on-terra-firma-to-support-them

  Senate bill adds funding for Army helicopter program and to buy more drones

  By: Aaron Mehta WASHINGTON — The Senate Armed Services Committee's version of the National Defense Authorization Act recommends increasing funding for the future long-range assault aircraft and to buy additional drones, according to a summary report released Thursday. On the whole, the senators seem to have focused more on programs from the Air Force and Navy, largely leaving the Army untouched, per the summary. However, full language has yet to be released. The Army requested $178 billion for fiscal 2021, down slightly from its fiscal 2020 request of $182 billion. The FLRAA program, which seeks a new long-range assault aircraft by 2030, is receiving $5 million more than was requested. It is the second year in a row Congress has increased funding for the program above what the Pentagon asked for, following a $76 million increase in FY20 to drive down technical risk and speed up delivery. FLRAA is one of two key programs for modernizing Army aviation. The Bell V-280 Valor tilt rotor and the Sikorsky-Boeing SB-1 Defiant coaxial are both contending for the FLRAA contract. The competition for the program of record will begin in 2022, with a plan to field the first unit equipped in 2030. The Senate is also adding $165 million for the purchase of additional MQ-1 unmanned aircraft for the Army to “meet state requirements for unmanned fixed wing ISR.” Additional language requires the secretary of the Army “submit a plan to operationally deploy or forward station in an operational theater or theaters” two batteries of interim cruise missile defense capability. On the cyber front, another $5 million is slated for Army operation and maintenance to “provide Cyber Mission Forces with more resources to access, operate, and train as required by increased operational demand.” Although not Army-specific, the NDAA language emphasizes the importance of the overall cyber posture, including an analysis of the Cyber Mission Force and an “evaluation of cyber reserve force options, which could provide capable surge capability and enable [the Department of Defense] to draw on cyber talent in the department sector.” Overall recruitment targets for the service is set at 485,000, adjusted own slightly from what the Army predicted in its FY21 budget request. https://www.defensenews.com/land/2020/06/11/senate-bill-adds-funding-to-army-helicopter-program-drones
