Harris Provides Lockheed with 7th GPS III Navigation Payload
Tuesday, June 11, 2019 | Comments

Harris provided Lockheed Martin with its seventh of 10 advanced navigation payloads contracted for the U.S. Air Force’s GPS III satellite program.

The GPS III navigation payload features a mission data unit (MDU) with a 70-percent digital design that links atomic clocks, radiation-hardened processors and powerful transmitters — enabling signals up to three times more accurate than any GPS satellites currently in operation. The payload also boosts signal power, which increases jamming resistance by eight times and helps extend the satellite’s lifespan.

In 2017, Harris completed development of an even more capable, fully digital MDU for the Air Force’s GPS III Follow On (GPS IIIF) program. The new GPS IIIF payload design will further enhance the satellite’s capabilities and performance.

In September, the U.S. Air Force selected Lockheed Martin for a fixed-price-type production contract for up to 22 GPS IIIF satellites. Harris is Lockheed Martin’s navigation signal partner for GPS IIIF satellites, and in January received a $243 million award to provide the navigation signals for the first two GPS IIIF satellites, space vehicles 11 and 12.
