SATELLITE ORBITS

Saturday, August 22nd, 2009

An orbit is a path along which a satellite moves far above surface of the earth. All earth satellites orbit around a point at the center of the earth. Orbits can be defined in categories, depending on altitude, eccentricity, inclination, and synchronization with the sun or other parameters.

A Dish Network satellite TV system is based off signals transmitted and received by multiple satellites. But, the main satellites in space are constantly moving in what is called an orbit.

Any object that moves around the earth has an orbit. The orbit is defined by 3 factors. The first is the shape of the orbit, which can be circular or elliptical. The second is the altitude of the orbit. The altitude is constant for a circular orbit but changes constantly for an elliptical orbit. The third factor is the angle the orbit makes with the equator. An orbit that brings the satellite over the poles or close to it has a large angle. An orbit that makes the satellite stay close to the equator has a small angle. Orbits depend on the mission the satellite was built for. The following orbits can be defined:
