Medium Earth Orbit
From Wikipedia, the free encyclopedia
Medium Earth Orbit (MEO), sometimes called Intermediate Circular Orbit (ICO), is the region of space around the Earth above low Earth orbit (2000 km) and below geostationary orbit (35,786 km).[1]
The most common use for satellites in this region is for navigation, such as the GPS (20,200 km) and Glonass (19,100 km) constellations. Communications satellites that cover the North and South Pole are also put in MEO.[2]
The orbital periods of MEO satellites range from about two to 12 hours.[3] Telstar, one of the first and most famous experimental satellites, orbited in MEO.[4]
