''Since GPS receivers work in the time and not in the frequency domain, they handle the velocity, gravity, and acceleration shifts differently than described above. First, each GPS space vehicle (SV) vlock is offset from its nominal rate by about -4.45 × 10^-10 (= -38 microseconds per day) to allow for the relativistic offsets between the differences between the SV and the ground. Of this -38 microseconds per day, about -45 are due to the gravitational potential difference between the SV at its mean distance and the earth's surface, and +7 to the mean SV speed, which is about 3.87 km/sec. (p. 193).

''The Theory of Relativity does not even assert that it would require significant adjustments to GPS timing:'' This sentence is wrong. It has shown to be wrong a couple of times, so it starts to become a lie. [[User:AugustO|AugustO]] 15:12, 6 April 2012 (EDT)
