  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

  Curtiss-Wright acquiring PacStar for $400 million

  Andrew Eversden WASHINGTON — North Carolina-based defense technology company Curtiss-Wright announced Sept. 24 that it had entered into an agreement to acquire Pacific Star, a major tactical communications vendor for the U.S. Army. Curtiss-Wright, based in North Carolina, bought PacStar for $400 million in an effort to boost its network communications business. According to a press release from Curtiss-Wright, PacStar's business will operate within the Curtiss-Wright defense business and is expected to generate $120 million in sales in 2020. “The acquisition of PacStar establishes Curtiss-Wright as a critical supplier of advanced tactical and enterprise network communications solutions supporting a broad spectrum of high-priority U.S. military force modernization programs,” said David C. Adams, chairman and CEO of Curtiss-Wright Corporation, in a statement. “The combination of Curtiss-Wright's mission-critical mobile and secure COTS-based processing, data management and communications technologies with PacStar's highly complementary hardware and software solutions will enable us to deliver best-in-class platform network integration and tactical data link network management to the warfighter.” Curtiss-Wright ranked No. 72 in Defense News' Top 100 annual report on the world's largest defense companies. PacStar is an important vendor for the Army's tactical network modernization effort, where it provides products to improve tactical expeditionary communications. Back in July, PacStar was awarded work to support the fielding of satellite baseband communications to three Expeditionary Signal Battalion-Enhanced (ESB-E) units by Army Program Executive Office Command, Control, Communications-Tactical. PacStar also provides networking and communications capabilities for the Marine Corps' Networking On-The-Move (NOTM) program. “PacStar, which represents the largest transaction in Curtiss-Wright's recent history, is well-positioned to benefit from the military's continued investment in robust, secure and integrated battlefield network management and is expected to yield significant opportunities for revenue growth," Adams said. "Further, this acquisition supports Curtiss-Wright's financial objectives for long-term profitable growth and strong free cash flow generation within our disciplined and balanced capital allocation strategy.” https://www.c4isrnet.com/industry/2020/09/25/curtiss-wright-acquiring-pacstar-for-400-million/
