Lockheed Martin wins up to $105M Space Force contract to modernize U.S. GPS ground control network

The U.S. Space Force awarded Lockheed Martin a contract worth up to $105 million to continue modernizing and sustaining the GPS ground control network. The work supports resilient positioning, navigation and timing (PNT) services for military and civilian users as the Next-Generation Operational Control Segment (OCX) winds down, including an upgrade to enable replacement of RTX’s troubled OCX program for future GPS IIIF spacecraft.

Briefing

What Hype is tracking

This award preserves continuity of U.S. GPS PNT by sustaining and upgrading the ground control network as Next-Gen OCX transitions, aligning with prior reporting on the OCX wind-down and Lockheed’s system role (source:c0e40213-da7f-44a9-ab7f-9ad6de8883cb).
It also addresses program risk tied to the OCX/ground-control modernization timeline by enabling Lockheed Martin’s AEP ground system to replace RTX’s long-troubled OCX path for future GPS IIIF birds—an approach that matters given earlier concerns over GPS ground-control contract delays and potential reassessment (source:9a902b16-cc53-42aa-886f-557b1952f799).
For defense and mission-critical users, the contract reinforces investment in anti-interference and resilience in GPS architecture—an emphasis consistent with Lockheed’s stated push to harden GPS upgrades against jamming threats (source:82114a38-4d6d-4c28-a7b0-6a4aec3789d8).
