Also called
geostationary, or simply
GEO, it refers to the
movement of
communications satellites
where the satellite circles the globe over the equator, in a movement that is
synchronized with the earth's rotation. Because of this synchronization, the
satellite appears to be stationary, and they also offer continuous operation in
the area of visibility. These types of satellite are said to have a
geostationary orbit, and it is the most common type of orbit for
communications satellites.
Bird is the slang term
given to a
communications satellite
that is in geosynchronous orbit.
