What are the types of satellite orbits?
There are at least three special types of orbits employed by modern satellites. These are the Geostationary Orbits, Low-Earth Orbits and Molniya types. A Geostationary Orbit satellite provides an illusion that it is stationary in a fixed location in space. Actually, it revolves around the planet once a day in the equator. It is useful for telecommunication devices especially those that rely on stationary antennas since there is no need to install special equipments for such facilities just to track the satellite. Meanwhile, Low-Earth Orbit satellites are located at least 400 Km above the Earth. Because of their lower altitude with respect to the ground, they can circle the Earth in only about 90 minutes. These satellites are less expensive and require less energy to receive and transmit data. On the other hand, the Molniya Orbit group of satellites operates at a certain inclined position suitable for Northern Altitudes. These Comsats were designed so that they will take more time servi
