| Nov 28, 2021 at 8:15 | comment | added | Carlo Beenakker | each observer will know its position relative to every other observer; they can then transform to, say, an earth-based reference frame, but only if they know the gravitational field. (Tarantola calls this the "attachment problem", distinct from the "positioning problem", which needs no knowledge of the gravitational field.) | |
| Nov 28, 2021 at 6:14 | comment | added | mathoverflowUser | @MichaelEngelhardt: Yes you are right, the satellites broadcast only their time. Suppose two observers, far apart, use two distinct sets of satellites. How do they transform from one coordinate system to the other? | |
| Nov 28, 2021 at 3:16 | comment | added | Michael Engelhardt | @stackExchangeUser - I don't see where Carlo wrote that "the satellites transmit their positions ...". They don't. The positions of the satellites aren't at issue and no other given coordinate system is being referenced. | |
