How many meters do the GPS satellites wander around?
Barney asked:
The satellites wander around and are stabilized with short “burns” of rocket fuel. How many meters do they wander before the ground station orders them to move? I would also strongly suspect (correct me if I am wrong) that the absolute position can be corrected in software to some extent. but with accuracies on the ground of 5 meters or so, I would think the satellites would have to be pretty stable. Yet on the other hand it’s hard to imagine those things being nailed to the sky.
