or the use of General Relativity in GPS satellite positioning

What a malfunction of clocks has to do with the fallacies of Relativity?
No journal in the world has the record of relativistic calculations of the effect of speed and gravity effects on atomic clocks BEFORE the clocks were sent to outer space.
Relativists asked L. Essen, the inventor of the atomic clock, permission to make tests on his clock. L. Essen consented it, and when he observed the "relativistic tests", L. Essen laughed of them, because they went to the ridiculous with their methods.
L. Essen even wrote letters mocking of Einstein and his followers, because their lack of experience and their famous thought experiments which are good for nothing.
The atomic clock mechanism includes an internal process of sending and receiving of signals that can suffer interferences by just moving the atomic clock in a fast vehicle. This is how sensitive these devices are.
The distorted but average data send by atomic clocks when in outer space was observed AFTER the devices were sent, and from here, adjustments were made to fix the problem, a receiver which will "translate" the received information to be updated in order to catch up with the data of the atomic clocks on ground zero.
All this experience has been a trial and error process, no calculations about this phenomenon in particular were made before, and the calculations made after the problem was observed, were made without the need of relativistic formulas... a simple college level calculator was enough.
Your words are similar to say that Jules Verne is the father of the submarine and the TV, and that thanks to him those are a reality.
Face it, the theory of relativity is pure fantasies.
