The U.S. Air Force’s third GPS III satellite in production flow at Lockheed Martin’s advanced satellite manufacturing facility in Denver is now fully integrated into a complete space vehicle.

GPS III Space Vehicle 03 (GPS III SV03) followed the first two GPS III satellites on a streamlined assembly and test production line. Technicians successfully integrated the satellite’s major components – its system module, navigation payload and propulsion core – into one fully-assembled space vehicle on August 14.

Next Tranche of GPS Satellites to be called GPS IIIFs

The Global Positioning Systems Directorate, which is poised to launch its procurement of another 22 GPS III satellites, has given its next tranche of spacecraft a name.

"We are officially calling this GPS IIIF," Col. Gerry Gleckel, the Directorate’s deputy director, told the November meeting of the National Space-Based Positioning, Navigation, and Timing (PNT) Advisory Board. "Just as there was a IIF that was the follow-on for the GPS II’s, this is the follow-on for the GPS III."

House and Senate authorizers are forcing a reorganization of the Pentagon’s management of military space programs, giving authority to a soon-to-be-named official to prioritize space budgets across services and setting planning in motion for a possible new department. They also approved spending the full amounts requested for the military GPS programs and mandated that defense officials both test a backup to GPS and look at incorporating European and Japanese GNSS signals into military user equipment.

Advisory Board Invites Ligado to the Podium

The nation’s leading satellite navigation experts have invited Ligado Networks, a firm whose plans are widely viewed by many as a threat to satnav, to present at their November 15 meeting. If the company accepts, it could illuminate the structure of the terrestrial service it has in mind and either ease, or add fuel to, the ongoing dispute between Ligado and the GPS community.

AFSPC Commander Holding Steady Through Sea of Changes

General John (Jay) Raymond

The ground was already shifting when Gen. John (Jay) Raymond took charge of Air Force Space Command (AFSPC) in October 2016. Just six months before, his predecessor Gen. John Hyten had announced the Space Enterprise Vision, a new way of approaching space asset development, management and protection now that space had become both contested and far more crowded. There were issues across the space, ground and user segments of the GPS program; sequestration was still looming and Congress was looking closely at how to reorganize the way the Air Force managed its space programs.
