geosynchronous

URL copied Share URL
  1. [astronomy] Positioned in an orbit moving west to east with an orbital period equal to the earth's rotational period. If a satellite is in a circular geosynchronous orbit in the equatorial plane, its orbit is geostationary. If it is not positioned directly over the equator, the satellite appears to make a figure eight once a day between the latitudes that correspond to its angle of inclination over the equator.
