Most of the communications satellites you know are in fact are geostationary satellites. A Geostationary satellite is like a geosynchronous satellite, they take 24 hours to complete a whole rotation.  However, they are positioned exactly 35,900 km above the Earth’s equator and their paths follow the equatorial plane of the Earth. A geostationary orbit or geostationary satellite is very similar to geosynchronous satellites. These satellites will not move North or South during the day; they are stationary and still, which is also permanently located just above the equator. These satellites are mostly used for communications and service, like weather forecasting, satellite TV, satellite radio and many other types of communications.
