U.S. Space Force Launches Final GPS III Satellite, Enhancing Global Positioning System Resilience

• •The GPS III SV-10 launch completes the series with 32 active satellites.
• •SV-10 enhances military capabilities with M-code technology for improved accuracy and anti-jamming.
• •The launch demonstrates rapid delivery capabilities through collaboration between the U.S. Space Force and Lockheed Martin.

On April 21, 2026, the U.S. Space Force successfully launched the final GPS III satellite, Space Vehicle 10 (SV-10), into medium Earth orbit using a SpaceX Falcon 9 rocket. This launch completes the GPS III series, enhancing the constellation to a total of 32 active satellites. SV-10 introduces critical advancements including M-code technology, which provides military users with three-times greater accuracy and eight-times stronger anti-jamming capabilities. The satellite also features an optical crosslink demonstration payload, allowing direct communication between satellites, which increases on-orbit resiliency. The launch marks the fourth consecutive GPS launch on an accelerated schedule, showcasing the collaboration between the U.S. Space Force and Lockheed Martin. The successful deployment of SV-10 sets the stage for the upcoming GPS IIIF generation, which will further enhance capabilities for both military and civilian users. The GPS III constellation aims to improve positioning and timing services for over six billion civilian users worldwide.
