Each orbit has a diferent velocity needed to maintain it
as you get further from the earth the velocity needed to maintain the orbit increases, but as you are traveling further the time taken to do one orbit also increases
At the orbital height of the shuttle / iss, one orbit takes 90mins or so
at Geostationary orbit, one orbit takes 24hours,
as the eath also takes 24 haours to rotate, when seen from the ground, a satelite in geostationary orbit appears to hover over a single point on the equator
