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?

According to relativity, both odometer readings are wrong. They do
not represent the true distance of the routes travelled because of the
length contraction effect.

They both represent the distance traveled according
to both Newton and GR.
