Lockheed Martin Space Systems, Newtown, Pennyslvania, along with industry partners ITT, Clifton, New Jersey, and General Dynamics of Gilbert, Arizona, have successfully completed 19 out of 71 PDRs for key GPS III spacecraft subsystems and assemblies. These include L-band transmitters, antennas, solar arrays, power regulation unit, all attitude control assemblies, as well as the Tracking Telemetry and Command (TT&C) subsystem and all TT&C assemblies. This effort will culminate in an overall GPS III Segment PDR in May to ensure the preliminary design meets warfighter and civil requirements prior to advancing into the Critical Design Review phase. The team is working under a $1.4 billion Development and Production contract awarded in May 2008 by the Global Positioning Systems Wing, Space and Missile Systems Center, Los Angeles Air Force Base, California, to produce the first two GPS IIIA satellites, with first launch projected for 2014. The contract also includes options for up to 10 additional spacecraft.

GPS IIA GPR Achieved By Lockheed Martin
The Lockheed Martin [NYSE: LMT] team developing the nexgen Global Positioning System (GPS) spacecraft, known as GPS III, is progressing on-schedule, achieving key milestones in the Preliminary Design Review (PDR) phase with the U.S. Air Force.
GPS III will improve position, navigation, and timing services and provide advanced anti-jam capabilities yielding superior system security, accuracy, and reliability. The first block of the new generation satellites, known as GPS IIIA, will deliver significant enhancements over current GPS space vehicles, including a new international civil signal (L1C), and increased M-Code anti-jam power with full earth coverage for military users. GPS IIIA also incorporates an aggressive capability insertion program that lowers technology and integration risks associated with the capabilities planned for future GPS III satellites. The capability insertion program will ensure a graceful growth path, minimizing re-design of the GPS IIIA satellites that are necessary to reach the full set of GPS III warfighter capabilities in future increments.
