What is a geostationary satellite?

Answer 1

Geostationary is the moving orbit in the plane of the equator. Geostationary satellites are 22,300 miles above the Earths surface, and remain stationary at a fixed point. Weather and communication satellites are examples of geostationary satellites.

Answer 2

A geostationary satellite is one that is in a fixed position relative to the Earth. This is usually achieved by putting the satellite in orbit over the equator at a speed which equals the speed of the Earth's rotation at the equator. This speed is only possible at a distance of about 7 Earth radii.
Satellite Television stations and GPS use geostationary satellites because the position of the satellites in the sky is fixed.

Answer 3

The satellite orbits at the same speed as the Earth, so it is always above the same part of the Earth. This type of orbit is also sometimes referred to as geosynchronous orbit.
