LEO (Low Earth Orbit)

Orbital plane located from several hundred to a few thousand miles about the earth’s surface. LEO systems can be regional or global and require many more satellites than GEO-based systems to provide service. Big LEO systems provide mobile satellite phone services and consist of satellite constellations of some 48 to 66 satellites. See also GEO and middle earth orbit (MEO).
