GPS III are the third generation of the U.S. Space Force's NAVSTAR Global Positioning System satellites. The GPS III development contract was awarded to a team led by Lockheed Martin. Block III will improve position, navigation, and timing services for warfighter and civil users yielding superior system security, accuracy and reliability. 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. Lockheed Martin's flight-proven A2100 bus serves as the GPS III spacecraft platform. Unlike the GPS IIF satellite, the GPS III satellite features an apogee propulsion system. The satellite features a LEROS-1C engine as an apogee propulsion system as well as 2 deployable solar arrays to generate power. ITT, Clifton, N.J. provides the navigation payload, and General Dynamics Advanced Information Systems, Gilbert, Ariz., provides the Network Communications Element (NCE) which includes the UHF Crosslink and Tracking Telemetry & Command (TT&C) subsystems.
