Lockheed Martin Completes Integration of GPS III Satellite
DENVER, CO: Lockheed Martin announces the successful completion of final integration of the US Air Force's (USAF) first next-generation Global Positioning System III (GPS III) satellite. The engineers and technicians lowered the system module into place over its propulsion core, successfully integrating the two into one space vehicle.
GPS III space vehicle one (SV 01) is an industry first with new, advanced GPS satellite design block for the Air Force. GPS III with more accuracy, improved anti-jamming capabilities and extend spacecraft life to 15 years. The new L1C civil signal also will make it the first GPS satellite interoperable with other international global navigation satellite systems.
The systems integration event brought together several major fully functional satellite components. The system module includes the navigation payload, which performs the primary positioning, navigation and timing mission. The functional bus contains sophisticated electronics that manage all satellite operations. The propulsion core allows the satellite to maneuver for operations on orbit.
“The final integration of the first GPS III satellite is a major milestone for the GPS III program,” says Mark Stewart, vice president of Lockheed Martin’s Navigation Systems mission area. “This summer, SV 01 will begin Thermal Vacuum testing, where it will be subjected to simulated harsh space environments. Successful completion of this testing is critical as it will help validate our design and manufacturing processes for all follow-on GPS III satellites.”
Lockheed Martin is currently under contract to build eight GPS III satellites at its GPS III Processing Facility near Denver, a factory specifically designed to streamline satellite production.
The GPS III team is led by the Global Positioning Systems Directorate at the U.S. Air Force Space and Missile Systems Center. Air Force Space Command’s 2nd Space Operations Squadron (2SOPS), based at Schriever Air Force Base, Colorado, manages and operates the GPS constellation for both civil and military users.
