Geo stationary satellite
The satellite which is known as earth-orbiting satellite is called geo stationary satellite. The geo stationary satellite is placed directly over the equator at an altitude of approximately 35,800 kilometers (22,300 miles) .The geo stationary satellite revolves in the same direction where earth rotates means from west to east. On this point one orbit takes exactly 24 hours to which we can say that same time length which is taken by earth to move once on its axis. The geo stationary satellite looks stationary as it is in the sky as it has been seen by the ground based observer. The new technology BGAN uses the GEO STATIONARY satellite for its global mobile communications network. It is at the 40 percent of earth surface from the Line of Sight. To access geo stationary satellite a directional antenna is used which seems to be as a small dish. It looks as the spot in the sky where satellite appears to be over. It have an advantage that it can be used without making any further adjustments.
