Satellite orbits are more or less stationary with respect to the “fixed” stars, not the rotating earth. Between successive 90 minute orbits, the earth will rotate approximately 22.5 degrees of longitude to the east, meaning, that for a person on the earth, the satellite will appear about 22.5 degrees in longitude further to the west between orbits. Over time, that satellite will cover almost the entire earth.
I realized I had left that out, and was mis-communicating when FR went dead. I just got back on, so I am now responding.
