communication satellites are placed in a geosynchronous orbit
How many geosynchronous satellites are there?
As of October 2018, there are approximately 446 active geosynchronous satellites, some of which are not operational. A geostationary satellite is in orbit around the Earth at an altitude where it orbits at the same rate as the Earth turns.
What is a geostationary satellite?
A satellite in a geostationary orbit appears stationary, always at the same point in the sky, to ground observers. Popularly or loosely, the term "geosynchronous" may be used to mean geostationary. Specifically, geosynchronous Earth orbit ( GEO) may be a synonym for geosynchronous equatorial orbit, or geostationary Earth orbit.
What is a special case of geosynchronous satellite?
A special case of geosynchronous satellite is the geostationary satellite, which has a geostationary orbit – a circular geosynchronous orbit directly above the Earth's equator. Another type of geosynchronous orbit used by satellites is the Tundra elliptical orbit .
What are geosynchronous satellites used for?
These satellites are commonly used for communication purposes, such as radio and television networks, back-haul, and direct broadcast. Traditional global navigation systems do not use geosynchronous satellites, but some SBAS navigation satellites do. A number of weather satellites are also present in geosynchronous orbits.
