Reply to comment by VTCifer 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

The citation is that I am a SME on avionics. All the GPS modules I have worked on have potential for 24 connections(channels) at a time, typically you will never see more than 18 at any one time. It is a one way connection yes, and they use something similar to frequency hop to effectively encrypt all but 3 or 4 for civilian use.

Edit: for further clarification, they have to recieve a steady signal before they use pings from any particular satellite. That confirmation process is what I am referring to as connecting.

"Pings"? And all this time I though it was a continuous binary phase-shift keying. More like a chirp or chipping.

Too many complicated words. Seems true.
