So the orbital speed of a satellite must be independent of its own mass, such that: So the orbital speed of a satellite must be independent of its own mass, such that:

A **geosynchronous** orbit is one that returns to its original position relative to the orbitee after one rotation of the orbitee.
A **geostationary** orbit is a geosynchronous orbit that always remains in the same position relative to the orbitee.
