GPS originated as a military protocol and has some level of encryption and authentication, but this is not available to the general public.
- GJim 2y agoGPS *had* no encryption or authentication; indeed, such security is only a recent addition to the L2 frequency. USK: Galileo also has authentication available on its civilian frequencies.
- lxgr 2y ago> such security is only a recent addition to the L2 frequency Is that already available? I thought GPS L2C didn't include authentication yet.
