Mission

USSF-106 is a mission for the United States Space Force. The launch will deploy various payloads directly into geosynchronous orbit, including the NTS-3 (Navigation Technology Satellite 3), a demonstration navigation satellite testing a new digital signal generator that can be reprogrammed on-orbit to broadcast new signals, improve performance by avoiding and defeating interference, and adding signatures for detecting spoofing attacks.
