Well, you may doubt it, however the designers of the system rely upon their understanding of, and the application of the consequence of both the theory of general and special relativity.

General relativity theory would say time passage is slower in a stronger gravitational versus a weaker one, thus the rate of time passage would be slower on the earth relative to the satellite.

Special relativity theory posits that a clock moving relative to another on earth would appear to run slower to an observer on earth.

Since the two do not exactly cancel out each other adjustments are constantly being made to account for the slight difference.

What cannot be doubted is that the satellite GPS system operates according the above.

At the beginning I wondered if you knew the difference, since I often find people who don’t. Since you do, I accept what you say.
