An early morning SpaceX launch on Tuesday marked the end of an era for the U.S. Space Force's navigation capabilities, delivering the tenth and final GPS III satellite to orbit while the Pentagon simultaneously canceled its troubled, multi-billion-dollar ground control system.
The successful launch of the Lockheed Martin-built GPS III Space Vehicle 10 aboard a Falcon 9 rocket from Cape Canaveral, Florida, completes a major modernization of the global positioning system. The mission solidifies SpaceX’s role as the go-to launch provider for national security, coming just a day after the Space Force terminated the long-delayed Next-Generation Operational Control System (OCX) from Raytheon, a program that had ballooned to a cost of $6.27 billion.
“With each GPS launch, the constellation becomes stronger and with SV 10, that is the 10th GPS III satellite that is equipped with a anti-jam capability that’s eight times stronger and three times more accurate than legacy spacecraft that’s on orbit today,” said Fang Qian, Vice President of Global Positioning System at Lockheed Martin, during a prelaunch media briefing.
The Falcon 9 rocket lifted off at 2:53 a.m. Eastern Time from Space Launch Complex 40. The first-stage booster, completing its seventh mission, landed successfully on the drone ship 'Just Read the Instructions' in the Atlantic Ocean. SpaceX announced this would be the final Falcon 9 landing for the drone ship, which will now be dedicated to future Starship operations after supporting 156 Falcon 9 landings since 2015. The completion of the GPS III constellation paves the way for the next generation of even more advanced GPS IIIF satellites, the first of which is expected to launch in 2027.
The GPS III SV10 satellite, nicknamed “Hedy Lamarr” by the Space Force in honor of the actress and inventor of frequency-hopping technology, brings significant upgrades to the network that serves billions of civilian and military users. Beyond the threefold increase in accuracy and eightfold improvement in anti-jamming capabilities, the satellite is a testbed for future technologies.
It is the first GPS satellite equipped with an optical crosslink payload, which will be tested with ground stations to enable direct satellite-to-satellite communication in the future. This technology is a safeguard against potential interruptions from ground control. SV10 also features a new digital atomic clock, providing a more robust and precise timekeeping standard that will be incorporated into the upcoming GPS IIIF series.
While the new satellite represents a leap forward in space, the ground segment suffered a major setback. On April 20, the Space Force announced the termination of the Raytheon-built OCX program. The system, first awarded in 2010, was meant to control the new GPS III satellites and their advanced features like the M-code signal but was plagued by a decade of delays and cost overruns.
“Despite repeated collaborative approaches by the entire government and contractor team, the challenges of onboarding the system in an operationally relevant timeline proved insurmountable,” said Col. Stephen Hobbs, commander of Mission Delta 31. “The analysis revealed additional investment in OCX was no longer the best solution.” The Space Force will instead continue to upgrade the existing, decades-old Architecture Evolution Plan (AEP) to operate the modernized constellation.
The successful GPS launch further cements SpaceX's position as the most reliable U.S. launch provider for national security missions, particularly as its competitors face significant hurdles. United Launch Alliance's Vulcan rocket has been grounded following an issue with its solid rocket boosters during a flight in February. Blue Origin's New Glenn rocket also suffered an upper-stage failure during its recent NG-3 mission, leading to an FAA-led investigation.
The Space Force has increasingly relied on SpaceX, shifting this GPS mission and three previous ones from other providers to the Falcon 9. The rapid three-month turnaround since the last GPS launch in January highlights the efficiency of SpaceX's flight-proven rocket fleet. The company has now launched 12 of the 14 missions flown under the National Security Space Launch (NSSL) Phase 2 contract and is dominating the awards for the subsequent Phase 3 contracts.
