According to relativists, GPS clocks GAIN 38us per day on the ground clock.
That is due to two components, 45us for gravity and -7us for relative speed.

Accordingly, an observer (OO) in GPS orbit would see the GC LOSING 52us per
day.

After one year, the OO would calculate that the OC was about 19ms ahead of the
GC.
However, the GO would calculate that his GC was only 13ms behind.

What happens when the clocks are reunited?
Who is right?

Two people drive different routes from city A to
city B. When they are reunited, one odometer reads
220 km and the other reads 230 km. Which one is
right?

Is Mr. Poe really as blind as Androcles has claimed you to be?

This is a classical case of the twin's paradox if you have not
realized it finally. It is absolutely impossible to resolve because
of the mathematics of the Lorentz transform.

Well, "impossible to resolve" except for the simple
resolution: That the two twins follow different world lines,
and thus the total elapsed time along those lines
is different.

Exactly analogous to my two odometers.
