I thought the GPS satellite constellation was made with a low precision on purpose, and that high precision GPS was only possible with a decryption key held by the american military? Does that mean the US opened their GPS keys, or does that mean there's another constellation of satellites (like Galileo) that is allowing that level of performance?
