Two federal efforts have been put on hold and experts with years of expertise in the PNT industry have retired, all changes that could affect the industry moving forward.
The current administration’s efforts to revamp the government could have a significant impact on the PNT community.

U.S. Space Force’s Space Systems Command (SSC) and Space Operations Command (SpOC) announced the expected launch of the National Security Space Launch (NSSL) GPS III-7 mission, Space Vehicle 08 (SV-08), with SpaceX’s Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Space Force Station, Fla., no earlier than the end of May 2025.

It is well-understood now that Global Navigation Satellite Systems (GNSS) are vulnerable to radio frequency interference (RFI) due to the very low power of their received signals. RFI can take the form of jamming, in which the GNSS frequencies are overwhelmed with unwanted power or spoofing, in which “fake” GNSS signals are transmitted.

The Federal Communications Commission (FCC) has issued a draft Notice of Inquiry (NOI) that, if adopted, will seek input on the development of alternative Positioning, Navigation, and Timing (PNT) technologies to complement GPS.
