Let's try to resolve this before deciding who if anyone is participating in politically motivated discrediting!

Wonderful, this is exactly the type of misinformation I was alluding to in my previous post. The derivations in the link oversimplify the problem by ignoring the actual relativistic effects and corrections used in GPS technology. The argument incorrectly assumes that the transmitter clocks' relative errors do not accumulate, which is not true in practice. The corrections for relativistic effects are essential for maintaining the synchronization of the satellite clocks with the ground-based reference clocks.

Each GPS satellite's clock drift must be calculated in its own reference frame to account for relativistic effects accurately. This is because the relative motion and gravitational potential of each satellite with respect to the Earth’s surface influence the rate at which time passes differently for each satellite. The math on PhysicsMyths is so oversimplified, it’s almost as if it were made for children. I suspect it may be Nazi propoganda. It completely ignores 100 years of experimental verification of relativity, the evidence for gravitational waves being the latest piece of the puzzle.

The European Space Agency explicitly states that they need to apply relativistic corrections to avoid drift. Do you think they are lying?
