>Civilian GPS has limited number of satellites they are authorized to connect to at a time. Military GPS can connect up to 24 satellites at a time for an accuracy better than 10cm with better response time. Still cool to see alternatives to DoD dependent technology.
Yeah, going to need a citation on that.
1- GPS receivers don't 'connect' to GPS satellites. The GPS satellites are (for the nature of receivers) broadcast only.
2- The US Air Force has only committed to keeping 24 satellites in total operational 95% of the time. There's actually only 31 actually flying satellites currently. No way you could receive signals from 77% of the satellites in orbit at the same time ~50% of them are going to be below the horizon at any given time, and they operate on line of sight. (?probably? slightly less than 50% due to curvature of the earth)

Reply to comment by Kooky_Support3624 in Researchers have developed an alternative positioning system that is more robust and accurate than GPS, especially in urban settings. The working prototype that demonstrated this new mobile network infrastructure achieved an accuracy of 10 centimeters. by the_phet
