The Space Force is paying Lockheed Martin $113.5 million to rebuild the ground-control software that keeps GPS working for everyone from Pentagon planners to airline pilots to cash registers running card readers, a move that clears the way for a new generation of jam-resistant GPS satellites to actually enter service. The company announced two task orders on September 10 covering the GPS ground segment — the network of control stations and software that commands the satellite constellation, as distinct from the spacecraft themselves. The larger award, worth $96 million, rewrites the ground-system controls needed to bring GPS IIIF payload satellites online. The second, worth $17.5 million, funds the first phase of an Architecture Evolution Plan (AEP) hardware and software refresh, according to GovConWire's reporting on the awards.
Neither task order buys a satellite. The Space Force already has GPS III and GPS IIIF spacecraft under contract with Lockheed Martin for production; this money instead goes toward the terrestrial half of the system — the operations centers, command software, and control links that tell the satellites what to do. Without a ground segment built to talk to them, the next-generation satellites cannot deliver the capability they were designed for, no matter how many of them reach orbit.
What the $96M Ground-Control Rebuild Actually Fixes
The $96 million task order targets the control software gap between today's operational ground system and the GPS IIIF satellites now moving toward launch. GPS IIIF is the follow-on to the GPS III satellites already flying, and it is built around M-Code, the military's encrypted, jam-resistant signal designed to keep positioning, navigation and timing (PNT) data usable in contested electromagnetic environments. A satellite broadcasting M-Code is only as useful as the ground system commanding it, and the current control infrastructure was not built with IIIF's expanded capability set in mind. This task order rebuilds those controls so the ground segment can actually operate the new payload once it reaches orbit, rather than treating the satellites as a bolt-on to an older command architecture.
Lockheed Martin has held the GPS ground-segment relationship with the Space Force for roughly a decade, running the system that keeps the existing GPS III constellation operational while newer satellites are built. "Over the past decade, Lockheed Martin has consistently delivered and sustained operational GPS ground capability, evolving the system to meet the most demanding warfighter and commercial requirements," said Christina Mancinelli, the company's vice president of global communications and navigation, in the September 10 announcement.
Why the $17.5M Architecture Evolution Plan Is Only Phase One
The smaller of the two task orders, $17.5 million, funds what Lockheed Martin and the Space Force are calling AEP x86 Phase 1 — the opening stage of a three-phase technology refresh of the GPS ground system's underlying hardware and software. The "x86" label points to a shift toward commercial-standard computing architecture inside a system that, like much of the Pentagon's legacy infrastructure, has historically run on purpose-built or aging hardware that becomes harder and more expensive to maintain, patch, and secure as it ages.
A phased refresh matters because the ground segment cannot go offline for a rebuild — it is continuously commanding an active satellite constellation that civilian infrastructure depends on. Breaking the modernization into three stages lets the Space Force and Lockheed Martin swap in newer computing architecture incrementally, verifying each phase against the live system before moving to the next, rather than attempting a single cutover that could interrupt PNT service. Phase 1's scope, per the company's announcement and GovConWire's independent reporting on the figures, covers the initial hardware and software groundwork; the second and third phases have not yet been awarded or priced publicly.
The Stakes Beyond the Military Mission
GPS is not a purely military system, and that is precisely why ground-segment reliability carries weight beyond the Space Force's own requirements. The same constellation and control infrastructure that supports M-Code military users also provides the timing signal that synchronizes financial transaction networks, the positioning data airlines and shipping companies route around, and the backbone timing reference telecom carriers use to keep cellular networks synchronized. A ground segment that cannot reliably command a resilient, anti-jam satellite constellation is a single point of failure sitting underneath a large slice of the U.S. and allied economy, not just a warfighting tool.
That dual dependency is also why the Space Force is modernizing the ground segment in tandem with, rather than after, the satellite production line. GPS IIIF's anti-jamming and signal-resilience improvements are only as good as the ground system's ability to command them, monitor their health, and maintain the constellation's availability for both military and civilian users simultaneously. The two task orders announced this week are aimed squarely at closing that gap before more IIIF satellites reach orbit.
What It Means for Contractors
The awards reinforce that Lockheed Martin's roughly decade-long hold on the GPS ground-segment mission is continuing rather than being recompeted piecemeal, at least for now — both task orders extend work the company already performs rather than opening new competitive ground. For contractors watching the broader GPS ecosystem, the more instructive signal is the funding pattern: the Space Force is willing to fund ground-segment modernization as a distinct, separately-priced line of work from satellite production, and it is doing so in deliberately small, phased increments (a three-stage AEP refresh, not a single large recapitalization) rather than one large modernization contract. That favors incumbents with established relationships and system knowledge who can execute quickly against tightly scoped task orders, and it signals that additional AEP phase awards — Phase 2 and Phase 3 of the x86 refresh — are likely to follow as the Space Force continues funding the ground segment incrementally. Companies positioning for ground-system, command-and-control, or legacy-hardware-modernization work elsewhere in the Space Force portfolio should note the pattern: phased, task-order-based funding tied directly to a specific satellite generation's operational readiness, rather than open competition for a fixed multi-year scope.
