To explain why DAVOUT's right:
Geostationary orbits work by having the satellite (artificial or not) orbit around the planet at the same speed as would the tip of a bar that extended the same distance away from the planet as the satellite - i.e. they stay over the same place. Now, as it is impossible to orbit around a latitude line, this has to occur at the equator.
