What must be understood is that if the theory of relativity did not exist, that is, if, at the base, the universe was isochronous even in a simple stationary frame of reference (there is no movement), there could be no GPS, because all the information would arrive at the same time, and we could not know how far away an object is from another.
It is precisely the isochrony of things that means that even if light is, for the receiver, an instantaneous transaction, that is to say it propagates infinitely quickly, there is nevertheless a time lag that means that we can measure the distance.
Distance IS the anisochrony of GPS.
It is absurd to say that GPS invalidates relativity, when it is relativity that allows GPS to exist.
Without anisochrony, no GPS. Only instantaneous transfers of information in a hyperplane of absolute simultaneity, and a total impossibility of calculating any delay of information due to distance.
