There are two types of satellites that are located in a foxed spot over earth the first is reconnaissance satellites for observation of earth and usually used by the military.. The second is earth observation satellites and are intended for environmental monitoring
An isochronous satellite is one that orbits the earth in one day. So it orbits the earth as the same speed as the earth rotates. Most satellites that are isochronous are infact geostationary satellites as they also stay in the same position above the earth. However these satellites occupy a very specific orbit above the equator. It is possible to have isochronous satellites that aren't geostationary however getting them to remain in orbit would prove difficult.
No satellites stays exactly still as they could not remain in orbit, but probably you are meaning a geostationary satellite. The orbit of these satellites matches the speed of the earth turning underneath them, so they remain above the same geographical point on the earth.
satellites are located 37,000 km above the earth's equator.
Stay above the same place on Earth "forever" ... thus they stay in the same place in our sky.
The speed of satellites varies depending on their distance from the Earth. The closer they are, the faster they must travel in order to remain in orbit.

Orbiting the Earth above the equator is true of geostationary weather satellites and they have infrared sensors to transmit images of the entire hemisphere continuously. All of those things are true except that while they are moving in orbit they appear motionless.
If they are in the atmosphere (low earth orbit), satellites are in the ionosphere. If they are in higher orbits, satellites are considered to be outside the atmosphere.
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.
Polar Orbiting.
A Satellite movement behaves in two ways. Its orbit may be defined either as "geosynchronous" or "geostationary". Geosynchronous satellites move together with the Earth's own orbit, so it revolves in the same way as the earth is. Geostationary satellites remain statically in place for a certain coordinate...
