low earth orbit
(redirected from Near-Earth orbit)

    Also found in: Wikipedia 0.04 sec.
(communications)low earth orbit - (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.

[Ovum report, "Applications for the superhighway", John Moroney].
