Space Law - Geostationary Orbit Allocation

Geostationary Orbit Allocation

Satellites in geostationary orbit must all occupy a single ring above the equator, approximately 35,800 km into space. The requirement to space these satellites apart means that there is a limited number of orbital "slots" available, thus only a limited number of satellites can be placed in geostationary orbit. This has led to conflict between different countries wishing access to the same orbital slots (countries at the same longitude but differing latitudes). These disputes are addressed through the ITU allocation mechanism. Countries located at the Earth's equator have also asserted their legal claim to control the use of space above their territory, notably in 1976, when many countries located at the Earth's equator created the Bogota Declaration, in which they asserted their legal claim to control the use of space above their territory.
