This program will improve position, navigation, and timing services for military and civil users worldwide, and will provide advanced anti-jam capabilities yielding superior system security, accuracy and reliability.

Under the $1.4 billion development & production contract, the team of Lockheed Martin Space Systems Co, ITT Corp and General Dynamics will produce eight GPS IIIA satellites, with first launch projected for 2014.

Eight GPS IIIB and sixteen GPS IIIC satellites are planned for later increments, with each increment including additional capabilities based on technical maturity.

When fully deployed, the GPS III constellation will feature a cross-linked command and control architecture, allowing the entire GPS constellation to be updated simultaneously from a single ground station.

Additionally,a new spot beam capability for enhanced military (M-Code) coverage and increased resistance to hostile jamming will be incorporated. These enhancements will contribute to improved accuracy and assured availability for military and civilian users worldwide.

The Lockheed Martin team designed and built 21 GPS IIR satellites for the Air Force and subsequently modernised eight of those spacecraft, designated GPS IIR-M, to enhance operations and navigation signal performance.

ITT Corp will provide the navigation payload, and General Dynamics Advanced Information Systems will provide the Network Communications Element (NCE) which includes the UHF Crosslink and Tracking Telemetry & Command (TT&C) subsystems.
