The Space Force and United Launch Alliance successfully launched the experimental NTS-3 satellite from Cape Canaveral, marking the first national security flight of ULA’s Vulcan rocket.

Built by L3Harris for the Air Force Research Lab and Space Systems Command, NTS-3 will test new positioning, navigation, and timing (PNT) technologies that could enhance future GPS satellites, ground systems, and user equipment.

Originally scheduled for 2022, the launch was delayed, allowing extended lab testing and the addition of new signals.

In orbit, NTS-3 will perform over 100 experiments, including GPS signal broadcast, autonomous operations, and anti-spoofing tests, Defense News has reported.

Successful technologies may be integrated into GPS IIIF satellites or future Resilient GPS small-satellite constellations.
