Harris Corporation to Offer Fully Digital GPS III Payload


Reading time ( words)

Harris Corporation has announced that it will offer an all-digital navigation payload for GPS III Space Vehicles (SV) 11 and beyond.

Harris’ fully digital navigation payload will add value to the U.S. Air Force’s GPS mission by offering enhanced performance and enabling on-orbit reprogramming. The all-digital payload expands on the advanced features of the current 70-percent digital solution Harris provides for Lockheed Martin’s GPS III SV 1-8 satellites. The features provide greater flexibility, affordability and accuracy versus existing satellites and include an advanced modular design, atomic clock timing systems, radiation-hardened computers and powerful transmitters.

The new payload combines innovative digital capabilities developed by Harris and Exelis, now a part of Harris. In 2013, Exelis successfully demonstrated digital navigation signal capability in a formal preliminary design review conducted by the Air Force. The payload also leverages the mature Technology Readiness Level 9 legacy Harris reconfigurable payload that is flying on the International Space Station and is incorporated on hosted payloads for the Iridium NEXT satellite.

“We are dedicated to the U.S. Air Force’s GPS mission and continue to invest our research and development funds to ensure performance that exceeds expectations and that is low risk to implement on future platforms,” said Bill Gattle, president, Harris Space & Intelligence Systems.

Harris has more than 500 digital processors on-orbit and another 150 awaiting launch. Harris navigation payloads have been on all of the 80-plus U.S. GPS satellites launched since the 1970s — with more than 750 years of on-orbit life without a payload-related failure. Harris has delivered more than 100 digital payloads, which have performed flawlessly on-orbit.

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.
