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.

Ushering in a new era of advanced Global Positioning System technology, the U.S. Air Force this week declared the first Lockheed Martin-built GPS III satellite “Available for Launch.”

The Air Force’s “AFL” declaration is the final acceptance of Lockheed Martin’s first GPS III Space Vehicle (GPS III SV01) prior to its expected 2018 launch. GPS III SV01 will bring new capabilities to U.S. and allied military forces, and a new civil signal that will improve future connectivity worldwide for commercial and civilian users.

GNSS Program Update: Dozens of NavSats Set to Launch in Next 40 Months

If all goes as planned the world’s satellite navigation providers will be launching dozens of satellites between now and the end of the decade.

The activity just this year and next is remarkable, said John Betz of the MITRE Corp., who co-chaired the panel with José- Ángel Ávila-Rodriguez of the European Space Agency.

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.

Air Force Awards Lockheed Martin GPS M-Code Early Use Ground System Upgrade Contract

Denver, Colorado-based Lockheed Martin announced that the U.S. Air Force awarded the company a $45.5 million contract to provide Military Code (M-Code) Early Use (MCEU) capability to the Global Positioning System (GPS). Part of the Air Force’s overall modernization plan for the GPS, M-Code is an advanced, new signal designed to improve anti-jamming and protection from spoofing, as well as to increase secure access, to military GPS signals for U.S. and allied armed forces.

Combined Spending Bill Unlikely to Impact GPS but Federal Shutdown Possible

The old quip about limitations refers to cramming 10 pounds of stuff into a five-pound sack. Congressional lawmakers must be wishing for something that easy as they get ready to return to work Sept. 5.
