Orbit class
Medium Earth Orbit (MEO)
Roughly 2,000–30,000 km. Where global navigation satellites live (GPS, GLONASS, Galileo, BeiDou).
207 cataloged objects in this orbit class.
Medium Earth Orbit covers altitudes between 2,000 km and the geosynchronous belt at ~35,786 km. Navigation constellations dominate here: GPS at ~20,200 km, GLONASS at ~19,100 km, Galileo at ~23,222 km, and the BeiDou MEO segment at ~21,500 km. Orbital periods run 11–14 hours.
