Global Navigation Satellite Systems Engineering, Policy, and Design
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.

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).

A: Radio frequency interference (RFI) events have grown in frequency and scope to become a paramount concern for commercial, military and (especially) safety-of-life critical applications of GNSS since the Russian invasion of Ukraine in February 2022 and the Hamas attack on Israel in October 2023.

Europe’s Galileo navigation system has taken a significant leap forward with the completion of a major upgrade to its Galileo Ground Segment. As one of the most complex ground segments ever developed in Europe, the challenge lay in seamlessly upgrading a system that serves more than four billion users globally—without disrupting service.
