the satellites first have to find their own individual position relative to fixed/known Earth fixed location beacons? Whitehouse is A, Pentagon is B, Al Gores house is C ... triangles, signal time, blah blah: I am here! Yeah stuff on Earth moves about too, so throw in a D, E, F ... it'll figure out what moved. (As long as someone doesn't shove all the beacons 1m to the left position should be pretty close.

The same way 2 or more satellites pinpoint your unknown location they first each pinpoint themslves based on Earth bound reference locations. (Vantage gives them line of sight to many.)

Same as someone called you looking for directions, you look around, "I'm at Billies Bar opposite the Post Office, where are you?" Them, "I'm at ..." You (knowing they can't see BB or the PO), "OK, head north on xx..."

Accuracy, yeah latency, atomic clocks ... still going to be air temperature [layers], clouds, even where the Sun is and what mood it's in at the time - the more [pref closer] points it can reference the more it can defactor a lot of that too.

Apparently one of the hardest things to fix is the satellites wobbling. Yeah they got gyro's and all that, but slow wobbles (thrown in harmonics...) are hard to measure while still discounting sensor noise and ...
