JULY 15, 2025 – The U.S. Space Force’s Space Operations Command accepted a modernized operating system for Global Positioning System, which is designed to maintain resiliency of the constellation and improve positioning, navigation and timing services to meet user demand now and in the future.
The GPS Next Generation Operational Control System upgrade is one of several current Space Systems Command acquisition programs, which, in aggregate, will deliver numerous modernized GPS III enterprise capabilities. The other programs include the GPS III/IIIF satellite vehicles and Military GPS User Equipment. These modernized enhancements will enable improved signal access in electronically impeded environments; improved ability to detect failures; improved position and time transfer accuracy; and improved capability ensuring integrity and uninterrupted availability of the military code.
“One of our missions is to deliver sustained, reliable GPS capabilities to America’s warfighters, our allies and civilian users. The current enterprise modernization efforts underway gives users confidence that GPS will continue to provide worldwide premier PNT service,” said Cordell DeLaPena, Space Systems Command program executive officer for Military Communications and Positioning, Navigation and Timing.
The Guardians in Mission Delta 31 partnered with SSC to develop a methodical process of transition exercises, transition rehearsals and constellation transfer trials to ensure the integrity and capability of the system prior to complete transfer, explained U.S. Space Force Col. Stephen Hobbs, MD 31 commander. “Additionally, there are risk reduction activities designed to demonstrate OCX’s ability to integrate using residual, on-orbit GPS satellites.”
OCX delivery was initiated by contractor Raytheon to the U.S. Government via the submission of the Department of Defense Form 250 on July 1, 2025. Upon acceptance of the system, MD 31 will continue integrated systems testing, Operational Readiness Exercises and preparation activities for the GPS constellation transfer.
“Testing and transition events will continue until the system is ready to transfer to operations, which is expected in late 2025,” said Hobbs. “Technology in space is advancing at lightning speed, with many new players from around the world. To continue providing reliable GPS for everyone – from your smartphone map to critical military operations –innovation is vital. Modernizing GPS is key in maintaining this essential service and remaining a leader in space.”
