This problem could be resolved within coordinate systems adaptations. I don't know if WGS84, the datum used in GPS, does it, but for example European official datum is ETRS89 which is very similar to WGS84, but adjusts coordinates to these tectonic movements, certain number of cm per year. The principle is to keep same coordinate numbers for same places, even through their global location has changed a bit, even over hundreds of years. In GPS world that does not matter really, but land survey deals with sub-cm accuracy and these things do matter.
