What do you know about GPS? Did you design it or something?
What's it matter what time it was received?
stamp_1 12:00:00.001
stamp_2 12:00:00.002
stamp_3 12:00.00.003
sstamp_1 12:00:00.002
sstamp_2 12:00:00.003
sstamp_3 12:00.00.004
sstamp - stamp = 0.001
stamp_2 - stamp_1 = 0.001
stamp_3 - stamp_1 = 0.001
stamp_3 - stamp_2 = 0.001
distance = (0.001 + 0.001)c

Well, to measure a time difference you would need the time stamp on
the received signal, and the TIME THAT SIGNAL WAS RECEIVED!
In rea;ity, the GPS receives signals from four satellites, and
calculates the travel time DIFFERENCE between pairs of satellite
signals, This produces three hyperboloids of revolution, which
intersect at two distinct points...
