teece it is perspective, in terms of what I described. (a velocity test)

The time is NOT changing in the GPS satellite because of velocity, but dimensional warp.
Each has to do with two different sections of the Theory of Relativity.

But the time comparisons between the two are:
1) Because of the speed it is moving away or towards the relatively stationary Earth position,
but for the most part it's a geostationary orbit. (this is minimal, if at all.)
2) Most important, the gravitational well is MUCH lower at about 23,000 miles above the Earth.
Thus yes, the clocks will go faster because the warp of space-time dimensions will be less in comparison
to the clocks at the deeper warp near the surface of the Earth.
Of course the difference is in milliseconds, but this is significant in GPS and telecomm packet transfer.

Not only did I know this because I was a Physics major and have been working with this branch of science for over 15 years, but also I worked as an analyst consulting the engineers for SPAWAR at the GPS library in San Diego for a year. And now I'm an analyst at a Satellite Telecommunications firm where one of our features for our mobile modems is GPS off the MSAT geostationary satellite.
