Origin: Greek prefix geo-
Geosynchronous has 2 different meanings across 1 category:
of or having an orbit with a fixed period of 24 hours (although the position in the orbit may not be fixed with respect to the earth)
Refers to the orbit of a satellite whose rate of revolution is matched to the rotation period of the Earth. A special case is the geostationary orbit which is circular and equatorial, so that the satellite appears to be fixed over a particular point on Earth's sky.
