Geosynchronous orbit

Its orbital period around the earth is one day.

It is at a height of (35000-36000) km above the equator of surface of the earth.

Example of the satellites are GPS.

It can be in an orbit of which is very close to the surface of the earther or very further away from the surface of the earth.

Example of the satellites are communication satellites.

it orbits the Earth in the direction follow the direction of Earth's rotation

Its orbital period is equal to the period of Earth's rotation

Its orbit is concentric to the equator

It rotates on its axis with a period same as the period of Earth's rotation
