A satellite in a geostationary orbit is basically an extension of the Lat/Long system into space as a sat hanging over a particular longitude on the surface is much like any object at sea level or on top of a mountain, for although rotational speeds at different in terms of height, they remain rotating with the Earth.

All geostationary satellites are at the same latitude: 0°. That is,
directly above the equator.
