низкая околоземная орбита
noun a usually circular orbit from about 90 to 600 miles (about 140 to 970 kilometers) above the earth
(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.
