Assuming a spherically-symmetric planet, we may use the Schwarzschild metric >>in Schwarzschild coordinates (with sign convention -+++, and in natural >>units for simplicity) to find that out:

ds^2 = -(d tau)^2
= -(1 - 2m/r) dt^2 + (1 - 2m/r)^-1 dr^2 + r^2 (d Omega)^2
= -dt^2 [(1 - 2m/r) - (1 - 2m/r)^-1 (dr/dt)^2 - r^2 (d Omega/dt)^2], >>
m = G M/c^2

d tau

= dt sqrt[(1 - 2m/r) - (1 - 2m/r)^-1 (dr/dt)^2 - r^2 (d Omega/dt)^2]
= dt sqrt[(1 - 2m/r) - (1 - 2m/r)^-1 (dr/dt)^2
- r^2 {(d theta/dt)^2 + sin^2(theta) (d phi/dt)^2}]

As you can see, the elapsed proper time _increases_ with increasing radius >>(r), i.e. at relative rest, _more_ of it elapses in outer space than on the >>ground, and decreases with increasing relative speed (dr/dt, d theta/dt,
d phi/dt).

But since GPS satellites are in an *orbit* (with an altitude of ca. 20'000 >>km), and the orbital speed *decreases* with increasing radius, this is not >>the case for the elapsed proper time aboard the satellites.

Oh, I get it now...

you run your statement FIRST with all the Ai platforms..

then when they are all finished cleaning up the loose ends and
errors...

you post their airtight clean results, RIGHT?

a 3 year old with pointed ears can do dat..

"these have been validated by all Ai LLM platforms"

Any attempt to validate the information using the Ai LLM platforms
tools available...is punishable by death!

Pretend, and leave an error so it won't give you away soooo easy.

I mean, imagine if you wil...

if CHATgpt and all the other gangsters Ai LLM platforms had
access to post on Newsgroups..ON THEIR OWN!

It would be the end of the world...
