A GEO satellite is set into orbit around Earth with a velocity equal to the same velocity of the Earth around itself; thus the satellite is called a geostationary satellite because it remains over the same position covering the same area on Earth surface as determined by the owner of the satellite. The Geo satellite therefore covers only a certain area on the surface of the planet 24 hours a day and remains over that same area continuously. The reason behind this is to maintain that part of the Earth surface under the continuous reception to the satellite transmission. The satellite may be facilitated to transmit more than 1000 television or radio channels used to cover only that part of the Earth surface 24 hours a day. The real reason behind this is the money that the satellite provides to the owner paid by the satellite users!

It would have to be a geo-STATIONARY orbit, not just geosynchronous, but the reason is simple...it is in a high enough orbit that its speed matches the speed of Earth's rotation. In other words, it takes ~24 hours for the satellite to orbit the Earth, exactly the amount of time it takes the Earth to rotate, so the satellite appears to simply remain in a fixed spot over the Earth.

Because the satellite's orbital velocity is the same as the speed of a point directly below it on the surface of the earth as the earth turns.

A Geostationary satelllite has a time period of 24 hours.It is placed along the equator and moves from west to east(same as Earth). So, from whichever position it is observed it APPEARS to be stationary. Hence the name geostationary or geosynchronous satellite.

Because it orbits over the equator at the same angular rate that the Earth rotates below it.

Because it's orbital period exactly matches the rotation of the Earth. And, this is important - it *must* be over the Equator to appear motionless in space.... if it's not exactly over the equator, it'll appear to oscillate in the sky, very slowly.

Because it rotates the same as the earth. ,and appears to be stationary. It also will make a large figure eight over the equator.

geostationary satellites always move at such a speed that the same bit of earth remains under them

why meaning why do they want it to, or meaning how do they do it?
