The Global Positioning System Next Generation Operational Ground Control System (GPS OCX) program is modernizing the ground control segment of the GPS system. It is being developed in three increments and will eventually allow the DOD to take full advantage of the capabilities offered by the various satellites.
The first increment is to deliver a capability to launch and initiate on-orbit testing of GPS III satellites; the next increment is to deliver a capability to command and control GPS II and GPS III satellites; and the final increment is to deliver a capability to make military and international signals operational.
Software challenges have delayed availability of the command and control capability. The first GPS OCX deliverable is scheduled to be complete in November 2014. The second deliverable, which is to provide command and control for GPS III satellites, is scheduled to be complete in October 2016, 9 months after the first GPS III satellite is available for launch.
