Harris Delivers Fourth GPS III Satellite Navigation Payload


Reading time ( words)

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 flawlessly through space vehicle integration and test – exceeding specification requirements.

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.

In November, Harris announced that it had completed development of a fully digital MDU for Lockheed Martin’s GPS III satellites 11 and beyond. The new SV 11+ payload design will provide enhanced capabilities and increased performance for the Air Force.

While the Air Force originally developed GPS for warfighters, millions of people around the world and billions of dollars of commerce now depend on the accurate, reliable signal created and sent by Harris navigation technology.

NASA's SOHO Celebrates 20 Years of Space-based Science

12/01/2015 | NASA
After 20 years in space, ESA and NASA’s Solar and Heliospheric Observatory, or SOHO, is still going strong. Originally launched in 1995 to study the sun and its influence out to the very edges of the solar system, SOHO revolutionized this field of science, known as heliophysics, providing the basis for nearly 5,000 scientific papers. SOHO also found an unexpected role as the greatest comet hunter of all time—reaching 3,000 comet discoveries in September 2015.
