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.

China Launches Two BeiDou-3 Satellites Featuring Accurate Rubidium Atomic Clocks

According to reports out of China, new, very accurate rubidium atomic clocks onboard two BeiDou-3 satellites launched into space on November 5 have greatly improved the accuracy of the system.

The country launched two BeiDou-3 satellites into space via a single carrier rocket to support its global navigation and positioning network at 11:45 UTC on Sunday (November 5). The satellites were aboard a Long March-3B carrier rocket which took off from Xichang Satellite Launch Center in the southwestern province of Sichuan, according to the China Xinhua News Agency.

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.
