USAF evolves GPS architecture with $800 million upgrade to ground control segment

On September 14, Air Force crews at Schriever AFB, Colorado, completed the initial phase of an $800 million upgrade to the GPS operational control segment.

Operators in the 2nd Space Operations Squadron (2SOPS) of the USAF 50th Space Wing migrated control of the GPS satellite constellation and ground monitoring facilities from a 1970s-era mainframe computer to a distributed IT infrastructure with advanced automated features. The 50th Space Wing, through the 2nd SOPS, performs the satellite command and control mission for the Global Positioning System.

It’s MBOC for common Galileo-GPS civil signal

The United States and the European Union (EU) have agreed to use the multiplexed binary offset carrier (MBOC) for a common GPS-Galileo signal for civilian use. In the future, this will enable combined GNSS receivers to track the GPS and Galileo signals with higher accuracy, even in challenging environments that include multipath, noise, and interference.

These signals will be implemented on the Galileo Open Service and the GPS IIIA new L1 civil signal known as L1C.

GPS Block III Contracts

The U.S. Air Force has awarded two $50 million contracts to Boeing and Lockheed Martin to execute a system design review for the next-generation GPS space segment program, GPS Block III.

The contracts come on the heels of both companies successfully completing system requirements reviews in November 2006. Those reviews, part of a $10 million follow-on order to a Phase A Concept Development Contract awarded in 2004, assessed Boeing’s and Lockheed’s ability to mitigate development and delivery risks associated with building the Block III satellites.

GPS: Launches of Satellites and Institutional Initiatives

Successful launch of the second modernized Block IIR satellite, IIR-15(M2), on September 25 and scheduling of another IIR-M launch on November 14 underlines recent progress in the GPS program.

IIR-15(M2), also identified by its space vehicle number (SVN58) and pseudorandom code number (PRN31), will be placed into orbital plane A, slot 2. The U.S. Air Force has designated the satellite to be launched in November as GPS IIR-16/M3, PRN15/SVN55.
