Geo Stationary Orbit

If the plane of the Geo Synchronous orbit is in the equatorial plane of the Earth and the body in that orbit rotates in the same direction as the Earth Rotates, then that orbiting body will always appear to be stationary to an observer standing on Earth's surface.It is then said to be Geo stationary orbit. this orbit is a particular type of Geo Synchronous orbit.

the concept of Geo Synchronous and Geo stationary not only applicable for Earth but also applicable for Every other planet in the galaxy and Natural satellites as long as they are rotating about an axis.

It is considered to be a circular orbit at a distance of about 35,786km from Earth surface.

This orbit is very much useful for
communication satellites,
broadcast satellites,
SBAS satellites (Satellite Based Augmentation System )
GNSS satellites (Global Navigation Satellite System) etc.,

Arthur Clarke , Author of several Science fiction books , had put forward this concept in 1945 , hence this referred to "Clarke's Orbit"

The first satellite to be placed in the Geo-Stationary orbit was Syncom-2 on July 26th 1963.
