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.

White House Defense Budget Proposes GPS Funds

The Bush Administration’s Fiscal Year 2007 (FY07) budget proposal for the Department of Defense (DoD), announced in February, allocates $315,314,000 in advanced technology development for GPS, including work on the GPS III program. If approved by Congress, that would represent a sizable increase from the FY06 expenditures of more than $85 million and $33 million in FY05.

GPS L2C is on the air

Civil GPS users now have a second full signal available to them — albeit on only one satellite and “at the user’s own risk” — courtesy of the first modernized Block IIR (IIR- 14M) spacecraft launched last September. And the world’s geodetic community is already moving to take advantage of it with announcement of an addendum to the receiver autonomous exchange (RINEX) format used to combine high-precision position data from different types of GPS receivers.
