GPS III Team Shifts Into CDR

The Lockheed Martin team developing the U.S. Air Force's Global Positioning System (GPS) III program has entered the Critical Design Review (CDR) stage on-schedule, an extensive phase that precedes production of the next-generation satellite system. Over the next year, Lockheed Martin Space Systems, Newtown, PA, along with industry partners ITT, and General Dynamics will conduct 70 individual CDRs for key GPS III spacecraft subsystems, assemblies and elements. The phase will culminate in the fall of 2010 with a final Space Vehicle CDR that will validate the detailed GPS III design to ensure it meets warfighter and civil requirements. GPS III will improve position, navigation and timing services and provide advanced anti-jam capabilities yielding superior system security, accuracy and reliability. The next generation GPS IIIA satellites will deliver significant improvements 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. Through precision location and timing information, the GPS constellation provides critical situational awareness and precision weapon guidance for the military and supports a wide range of civil, scientific and commercial functions - including air traffic control.
