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.
