A hermit living up on the mountain decided to go down to replenish daily necessities, including shoes. According to the size of his own feet, he cut some pieces of rope for the measurement of future shoes. A total of five shoes of different materialsare needed, and he prepares five pieces of ropes of different materials accordingly. At the shoe store down the mountain, there were problems: the rope had shrunk and no longer reflected the size of his feet.
Fortunately, the hermit is an excellent relativity expert. He took out the scientific instruments he carried and measured the local temperature, humidity, and atmospheric pressure. In particular, he didn't leave out the local altitude, which affectsEarth's gravitational force, something relativity theorists are particularly fond of, and one of the factors that causes the rope to shrink.
After a series of complex and dizzying scientific operations, considering all the above-mentioned physical environmental factors, of which the gravitation is just few tiny parts, the excellent scientist reached the adjusted length of final version andre-marked the five ropes. He proudly handed it over to the shopkeeper, although those calculations make no sense since factors are too complicated to consider.
Without saying a word, the shopkeeper immediately threw the unusable ropes directly into the trash can. The shopkeeper simply took off the physicist's shoes, and quickly measured the size of his feet while the great physicist was struggling to persuadethe bourgeoisie of the beauty of General Relativity.
Above is just what happening of Relative theory in application of GPS in 2022.

But the gravitational twin paradox is easily measurable these days,
as shown on a hermit's portable atomic clock,
and it agrees with the predictions of general relativity.

My Dear Jan
a physical device runs slower caused by any physical factor does not mean TIME gets slower.
lot of physical factors cause physical device (among which some is called clock) run slower. That does not mean time get slower.
as far as gravity is concern, Gravity cause some clock faster, such as pendulum clock and plasm clock ; Gravity cause some clock slower, such as atom clock. Different type of clock just behave opposite. So which clock reading is the time?

That means UTC is stable, and GPS always need to synchronized! thanks for supporting me.It's actually the other way around, TAI/GPS time are stable but UTC has
to have a leap second added or subtracted once in a while to stay in
synch with our wobbly old earth.

themselves. They "tick" at a different rate to compensate for GR effects
and their signal gets received on earth at the right frequency)

The point here is : all the satellite clock must synchronized to the one standard clock in base station in the Earth.

TICK RATE. In physics time is what clocks measure, and does not change, either.
A fable:
A physicist wants to build a laboratory, and use all the usual reference books, in particular the spectroscopy handbook that lists the
frequencies of thousands of atomic transitions with 12 significant
digits (or more when known). If they build the laboratory on earth's
geoid, then they can use TAI as time-base for their measurements,
because TAI is valid on the geoid. If they build the laboratory on a mountaintop, they CANNOT use TAI, because all the measurements will be
wrong -- TAI is not valid there. So the mountaintop physicist has two choices: use a local atomic clock as a time-base, or use GR to correct
TAI for the altitude.
[I ignore the difficulties of obtaining TAI as a time-base
in a laboratory. GPS time is vastly easier, and in practice
is usually used, but it has the same issues.]
The point is that the laws of physics are all local, so one must use a
local clock, and TAI is not local. Ditto for UTC and GPS time. In our
every day lives this is not an issue, but a physicist making timing measurements accurate to 12 digits MUST deal with it.

Never mind GPS, how would you use one satellite to know where you are on the equator? The satellite is geostationary somewhere above the equator. (I do not know how a geostationary satellited above the North Pole would look like)
