  Space Force awards $253.6M contract for protected comms

  By: Nathan Strout The Space Force awarded Northrop Grumman a $253.6 million contract to develop a payload that would provide a higher level of protection to war fighters relying on satellite communications on the battlefield. The contract is for the Protected Tactical SATCOM payload, the service announced Feb. 12. Protected Tactical SATCOM (PTS) is the Space Force's planned next generation anti-jamming satellite system, which will provide tactical communications for war fighters all over the world — including the polar regions — using the Protected Tactical Waveform. As PTS is developed, the Space Force plans to begin offering Protected Tactical Waveform communications over the Wideband Global SATCOM system and later commercial satellites systems. The Space Force said in a statement it will award up to four payload development contracts. According to the FY 2021 Space Force budget request, the service is employing a spiral development strategy that will incrementally deploy prototypes progressively demonstrating new anti-jamming technologies. The payloads will be designed to potentially be hosted on other satellites as a cost saving measure. The contract was awarded through the Space Enterprise Consortium. “We are excited to partner with Northrop Grumman to enable the rapid development of a protected communications prototype payload,” said Col. Dennis O. Bythewood, program executive officer for the Space and Missile Systems Center's Development Corps. “The technology maturation and prototyping effort conducted under the SpEC (Space Enterprise Consortium) Other Transaction Agreement will allow SMC to harness the innovation of partnerships between traditional defense and non-traditional/small business contractors with a projected on-orbit capability three years earlier than a traditional acquisition.” https://www.c4isrnet.com/battlefield-tech/space/2020/02/13/space-force-awards-2536m-protected-tactical-satcom-contract

  Air Force’s next GPS satellite ready to boost accuracy, anti-jamming capabilities

  By: Daniel Cebul Lockheed's Martin second GPS III satellite has passed all of the U.S. Air Force's technical and safety tests and is ready to be launched, likely in 2019, according to a company statement Aug. 21. The statement marks the formal designation that the satellite is “available for launch.” The first GPS III satellite was available for launch in September 2017 aboard a SpaceX Falcon 9 rocket and is set to liftoff from Cape Canaveral Air Force Station in Florida before the end of 2018. The next satellite will launch aboard a rocket from United Launch Alliance. The new satellite constellation is expected to be a significant improvement over the current generation of satellites. According to Harris Corp., the company that provides Lockheed Martin with the satellites navigation payload, the next-gen satellites are equipped with “a Mission Data Unit (MDU) with a unique 70 percent digital design that links atomic clocks, radiation-hardened computers and powerful transmitters." This allows for signals three times more accurate than those on current GPS satellites, the company said. In addition to being more accurate, the satellite is also eight times more resistant to jamming. This model also adds and maintains signals to ensure compatibility with Global Navigation Satellite Systems and provide stronger signal integrity. Harris also unveiled an upgraded payload in November 2017 to be used for the Air Force's GPS III Follow On (GPS IIIF) program, which will begin with the 11th GPS III satellite. This next-gen payload will grant the clock signal for a new GPS III Search and Rescue (SAR) payload, and extend the satellite's service life. Lockheed Martin is expected to be the prime contractor. In June, the third GPS III satellite completed thermal vacuum and environmental testing to simulate how the satellite will hold up in the space's unforgiving environment. https://www.c4isrnet.com/c2-comms/satellites/2018/08/21/air-forces-next-gps-satellite-ready-to-boost-accuracy-anti-jamming-capabilities
