Harris delivers fifth GPS III payload
Harris Corporation has delivered the fifth of ten contracted advanced navigation payloads to Lockheed Martin for the US Air Force’s GPS III satellite programme, the company announced on 4 June.
The GPS III navigation payload features a Mission Data Unit (MDU) with a 70% digital design that links atomic clocks, radiation-hardened computers and powerful transmitters, enabling signals three times more accurate than those on current GPS satellites. The payload also boosts satellite signal power, increases jamming resistance and helps extend the satellite’s lifespan.
Lockheed Martin has successfully integrated the navigation payload into the fifth GPS III space vehicle, GPS III SV05.
Four navigation payloads have already been fully integrated on GPS III SV01-SV04. Harris will deliver three more payloads by the first quarter of calendar year 2019 for GPS III space vehicles 06-08.
