Boeing said June 5 it is teaming with Raytheon and Harris Corp. to pursue a contract the U.S. Air Force intends to award this year for sustainment work on the current generation of ground hardware and software that controls the nationโ€™s fleet of GPS navigation satellites.

The Air Force plans to release a request for proposals June 19 for the GPS Control Segment Sustainment (GCSS) contract, which will extend the current GPS Operational Control Segment until it transitions to the next-generation system, GPS OCX, which has experienced delays. Raytheon Intelligence and Information Systems of Aurora, Colo., was awarded a nearly $900 million contract for GPS OCX in February 2010.

Boeing, Raytheon and Harris signed an agreement to pursue the GCSS contract as a team in early May, according to Boeing spokeswoman Lynn Farrow. Other team members include CRGT, Infinity Systems Engineering, Boecore, Expert Methods Inc., a.i. Solutions and RT Logic.

โ€œThis team brings together the best of industry in the current GPS sustainment effort and ensures a smooth transition to the next-generation system,โ€ Sparky Olsen, the director of Boeing Mission Operations, said in a statement.

OCX is being developed to operate the next-generation GPS 3 satellites being built by Lockheed Martin Space Systems under a billion dollar prime contract the Denver-based company won in 2008 by beating Boeing, which built the generation of GP Ssatellites that are currently being launched.

The Boeing-built GPS 2F-3 satellite is scheduled to launch in October on a United Launch Alliance Delta 4 rocket. Next March, a United Launch Alliance Atlas 5 is slated to carry GPS 2F-4 to orbit.

The Air Force expects to launch the first GPS 3 satellite in 2015.
