Also a geosync orbit like the one you described is only possible above the equator. Of course you could have orbits at other inclinations and eccentricities that take 24 hours but the objects on those orbits would not appear to stay in the same spot in the sky.
my point was that they can appear to hover in one spot from the ground, not that they are actually hovering..
