USSF-106 (NTS-3 & USA-554)

NTS-3 (Navigation Technology Satellite 3) is a demonstration navigation satellite. NTS-3 will experiment with a new digital signal generator that can be reprogrammed on-orbit, enabling it to broadcast new signals, improve performance by avoiding and defeating interference, and adding signatures for detecting spoofing attacks. NTS-3 will be the aft payload on the USSF-106 mission.

USSF-106 also launched a classified payload for the United States Space Force identified as USA-554 by the US government.
