Lockheed Martin and the U.S. Space Force launched GPS III Space Vehicle 10 (SV10) in the early hours of April 21, elevating the Global Positioning System constellation to its strongest configuration to date and completing the GPS III series. The spacecraft lifted off from Cape Canaveral Space Force Station at 2:53 a.m. Eastern time, acquired its signal soon after, and is being managed at Lockheed Martin’s Launch & Checkout Operations Center in Denver pending formal acceptance into the GPS operational control network.
SV10 carries an optical crosslink demonstration payload designed to test satellite-to-satellite laser communications, a capability intended to bolster on-orbit resiliency by allowing GPS spacecraft to communicate directly with one another. The satellite also includes a demonstration Digital Rubidium Atomic Frequency Standard clock to support highly precise and reliable timekeeping.
The mission marks the fourth consecutive GPS launch on an accelerated schedule, underscoring a push to rapidly deliver new on-orbit capabilities to military users. GPS III satellites provide significant upgrades over earlier generations, including three-times greater accuracy, eight-times stronger anti-jamming, and secure M‑Code signals for military operations. For civilian applications, the enhancements are intended to improve smartphone navigation, speed emergency response location services, and provide more precise timing for financial markets and telecommunications.
“The final GPS III deployment is an important milestone as we continue strengthening the GPS constellation,” said Fang Qian, vice president of GPS at Lockheed Martin. “By launching SV10 into orbit, we’re not only adding to the resiliency of today’s GPS capabilities – we’re opening the door to the next generation of GPS IIIF satellites that will provide greater resiliency and serve as the backbone of the GPS constellation for years to come.”
With SV10 on orbit, Lockheed Martin is shifting focus to production of the next-generation GPS IIIF series. Those satellites are designed to add new capabilities and further harden the constellation’s resilience, including Regional Military Protection intended to deliver more than a 60-fold increase in anti-jamming performance. The company is building the IIIF spacecraft at its Denver facility, applying emerging tools such as augmented reality and digital twins, and is under contract to produce 12 satellites in the block.
More than 30 GPS satellites currently operate in orbit, providing positioning, navigation and timing services to military, civilian and commercial users worldwide. The system continues to serve billions of people as a trusted space-based navigation infrastructure.
