What is a geostation satellite?

Answer 1

Geostationary satellites orbit high above the surface of the earth at about 35,000km, directly above the equator. The take the same time to complete one orbit as the earths surface as it rotates meaning it is always above the same point on earth. They are used for TV and telephone signals as well as weather imagery, among other things.

A satellites period, the time it takes it to go around the earth, is determined, in part, by its altitude.

The further away it is then the longer it will take.

You can calculate an altitude where it will take just one day to make an orbit. If this is done then though the satellite orbits the earth it appears to be stationary above one point of the earth. This orbit must be above, or very near to, the equator. For the earth this altitude is approximately 36,000 km (22,000 miles)

Answer 2

Satellites in geosynchronous orbit stay above the same point on earth's surface at all times. This means that the period of the satellite in its orbit of the earth is exactly the same as the period of the earth's rotation.

_____________________________________

Geosynchronous; geo = Earth, syn = equal, and Chronos was the Greek titan in charge of time. So geosynchronous means " equal time with Earth"; the satellite orbits the Earth in the same amount of time that the Earth spins. So a geosynchronous orbit is one in which the satellite takes exactly the same amount of time as the Earth to turn, and the satellite seems to hang suspended in space.

This means that a satellite dish pointed at the satellite doesn't need to track the satellite, which does not seem to move.

Answer 3

They're usually called "geostationARY satellites". If you were to stand on the earth's equator and look straight at a geostationary satellite, it would appear to stay in exactly the same place - with the sun, moon and stars moving all around it.

Answer 4

Geostationary satellites hoover over the same place, having a period of 24 hours.
