COLORADO SPRINGS, Colo. Lockheed Martin officials signed a contract with the U.S. Air Force to continue to sustain and further modernize the Global Positioning System (GPS) satellite constellation?s ground control system through 2025.

Under the follow-on GPS Control Segment Sustainment II (GCS II) contract, the continued upgrade of the GPS Architecture Evolution Plan Operational Control Segment (AEP OCS) will allow GPS’ legacy ground control system to support GPS III satellite on-orbit operations, developed under the GPS III Contingency Operations (COps) program.

COps will enable the AEP OCS to support the positioning, navigation and timing missions of the Air Force’s new GPS III satellites, which began launching in 2018. In addition, GCS II will sustain the operational M-code capability being deployed in 2020 that is in development under the M-code Early Use (MCEU) contract. Operational M-code is a critical warfighter capability to support missions in contested environments.

Under the original GCS contract awarded in 2013, Lockheed Martin executed numerous engineering modifications to the OCS, including the COTS Upgrade 3(CUP3)/Ground Antenna Air Force Satellite Control Network (AFSCN) Interface Technology Refresh (GAITR) upgrade, the Remote Site COTS Network (RSCN) project, the GPS Information Protection Reinforcement (GIPR) project, the COTS Upgrade #2 (CUP2) project, and Red Dragon Cybersecurity Suite (RDCSS). These projects modernized the infrastructure, improved the cyber posture and added mission capability. The GCS II contract continues that commitment to evolving the OCS to address today’s mission needs.

Under GCS II, Lockheed Martin officials say they will continue to manage the technical baselines for the OCS and GPS Information Network (GIN) and regularly procure, develop, fabricate, integrate, test, and install software and hardware modifications into the GPS operational baseline. Focus areas will be performing a technical refresh of the GIN and increasing the resiliency of the OCS.
