How does encryption work on GPS signals? Since it seems the military have access to better accuracy, it’s not just a wavelength that is broadcasted.

- jdietrich 3y agoPrior to 2000, the civilian signal (C/A code) was deliberately degraded by the addition of small random variations in the time signal, but this is no longer the case. A separate military signal (P-code) still exists, which is encrypted in order to prevent spoofing; to my knowledge, the encryption scheme used for the military signal is still classified.
