low Earth orbit

(LEO) An orbit around the Earth of a satellite, etc., at an altitude of less than 5500 km.

low earth orbit

(communications)
(LEO) The kind of orbit used by communications satellites that will offer high bandwidth for video on demand, television, and Internet communications. A satellite in LEO, in contrast to one in a geostationary orbit, is not in a fixed position relative to the Earth's surface so several satellites are required to provide continuous service.
