Oct 15, 2019 at 8:45 comment added pinpon "(for military use)" This is a common misconception. Several manufacturers were able in the past to reverse-engineering the signal on the second frequency of GPS (enabling cm level precision). Furthermore, the new GPS band (L5) does not have encryption, and new open signal are being deployed also on the L2 band.
Nov 13, 2011 at 20:56 comment added anna v @BenCrowell if you read a bit about GPS, they also have general relativity corrections so they would not ignore the obvious.
Nov 13, 2011 at 19:49 comment added user4552 "GPS takes into account all the relative motions[...]" I think it would be more accurate to say that GPS takes into account the relative motions that are relevant, and doesn't need to take into account the relevant motions that are not relevant (such as the earth's orbital motion around the sun). The distinction between the two is important. This has to do with the notion of an inertial frame in GR, which is different from that in Newtonian mechanics.
Nov 13, 2011 at 12:34 comment added anna v @BenCrowell The answer is in the link in the first words. GPS takes into account all the relative motions and they used the GPS definitions.
