sentences:  Such satellites are often used for communication purposes; a geosynchronous network is a communication network based on communication with or through geosynchronous satellites.A common misconception about geosynchronous satelites is that there can be such satelites on every point above Earth surface it is not true as a "component" of gravitational pull is always acting, parallel to rotational axis of the planet, on the satellite which can never be balanced by centrifugal force as centrifugal force is only and always perpendicular to the rotational axis of the planet.However, on the equator of earth, there is no gravitational pull's component acting on the satellite parallel to rotational axis and only gravitational pull is perpendicular to the axis of rotation which is balanced by satellite's centrifugal force.
