August 2025: With rising concerns on the vulnerability of GNSS, the FCC seeks to explore solutions to improve the robustness of PNT services. SpaceX argues that the Starlink system may support the FCC’s interest in a ‘layered’ approach to national PNT resilience by providing secure, reliable, and global coverage.
“It looks like SpaceX has come around to viewing PNT as ‘today’s problem’,” says the RNL’s Dr. Humphreys, “But what’s interesting about their recent comment is an emphasis on… D2C signals for PNT rather than the Ku-band broadband signals.” He says that at present, “Starlink’s timing in the Ku band is so irregular that accurate pseudorange-based PNT is not possible,” as can be seen in a recent paper from the RNL.
