Thousands of planes and ships are facing GPS jamming and spoofing. Experts warn these attacks could potentially impact critical infrastructure, communication networks, and more.
Planes only use GPS because GPS has a very rigorous signal integrity program that others don’t have. The “safety of life” requirements on GPS are onerous. Also, GPS has both L1 C/A and L5 (not enough L1C or L2C to be useful yet) signals. I don’t think Galileo or GLONASS have extra signals, but I think Beidou does (not an expert on other systems).
Just this January, ESA completed the safety of life analysis requirements for Galileo to be used as a civil aviation signal.
