Medium earth orbit (MEO) satellites lie between the two Van Allen Belts. MEOs are also called Intermediate Circular Orbits (ICOs).The altitudes of these satellites range from 2, 000 km to 35, 000 km, i.e. above the low earth orbits and below the geosynchronous orbits. The orbital periods of MEOs range from 2 hours to more than 23 hours, depending upon their attitudes.Types of MEOs according to orbitsMEOs with circular orbits − They revolve at constant speed at an constant altitude.MEOs with elliptical orbits − Lowest altitude is called perigee and the speed is highest here. Highest altitude is called apogee ...
