Geostationary Orbit

"To achieve a geostationary orbit, a geosynchronous orbit is chosen with an eccentricity of zero, and an inclination of either zero, right on the equator, or else low enough that the spacecraft can use propulsive means to constrain the spacecraft's apparent position so it hangs seemingly motionless above a point on Earth. [...] The orbit can then be called geostationary. This orbit is ideal for certain kinds of communication satellites and meteorological satellites."
