Disposal orbit
Appearance
A disposal orbit is an orbit a little above geostationary orbit (GEO) where satellites are sent once they have passed their useful life.
According to regulations from the Federal Communications Commission, any satellite in GEO must be moved farther away from the Earth at the end of its useful life. A complicated formula determines how high the satellite must go to reach a suitable disposal orbit, but most end up about 300 km above where they started.
