Harris Delivers Navigation Payload for GPS Space Vehicle
Friday, December 15, 2017 | Comments

Harris delivered the advanced navigation payload for the fourth GPS III space vehicle (SV04) to Lockheed Martin in October. Harris delivered two payloads in 2017 and is committed to delivering four more in 2018.

Harris is under contract with Lockheed Martin for 10 GPS III navigation payloads. The first payload is fully integrated on the U.S. Air Force’s first GPS III satellite, GPS III SV01, which was declared available for launch in September, with an expected launch in 2018. The payload moved through space vehicle integration and test exceeding specification requirements, a statement said.

Harris’ second, third and fourth navigation payloads have been fully integrated on GPS III SV02, SV03 and SV04. The fifth payload for SV05 is in process of environmental testing.

At the heart of Harris’ navigation payloads is a mission data unit (MDU), featuring a unique 70-percent digital design that links atomic clocks, radiation-hardened computers and powerful transmitters — enabling signals three times more accurate than those on current GPS satellites. These payloads also boost satellite signal power, increase jamming resistance by eight times and help extend the satellite’s lifespan.
