Here is GPS math with an embedded spreadsheet to calculate solutions:

There is some argument about calculating distances from the GPS receiver and
the 3 satellites. The solution to this is the satellites send a time stamp
with their signal. Consequently the only atomic clocks required are on
board the satellites themselves and not on every receiver. At that the
satellites need only be updated by an atomic clock. This is how distances
are calculated. Once they're determined, the GPS coordinates can be found
with just the coordinates of the satellites. This web page I made shows
how.
