Global Navigation Satellite Systems Engineering, Policy, and Design
Slated for 2031, the NovaMoon lunar in-orbit demonstrator and reference station will provide a lunar-based local differential, geodetic and timing station to enhance the accuracy of lunar PNT services to sub-meter levels across the South Pole.

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.

This follow-up to a 2007 Inside GNSS article looking at the potential future role for C-band in navigation details how, nearly 20 years later, it’s moved from an interesting idea to critical for resilient position, navigation and timing (PNT).

Beginning in September, Controlled Reception Pattern Antennas (CRPA), a highly effective anti-jam technique, will no longer fall under stringent International Traffic in Arms Regulations (ITAR)—finally opening the market to U.S. manufacturers and expanding use of the technology.
