Geostationary satellites orbit the earth at the same rate as the earth rotates. They do not move position viewed from the ground. That is why they are used for all GPS devices. If they moved there would be no GPS devices. Just GOOGLE geostationary for details. Actually the GPS satellites are not Geostationary. They are in orbits at one-half the geostationary altitude. Here is a link to the explanation: GPS.gov It is mainly communications satellites that are in a geostationary orbit that exactly matches the speed of the earth's rotation so they remain above the same spot on the earth.
