The most common satellite orbits are: the geostationary orbit and the polar orbit, where fixed satellites are launched from west to east over the equator, always appear on the same site, moving In the same direction, the same Justice in a circular motion around the Earth, as the satellite travels around the pole in the direction of the north and south pole to pole, and the Earth rotates underneath work a full scan of the globe through one bar and one time.
