Satellite Systems can be classified based upon their orbits as low earth orbit, medium earth orbit & geostationary earth orbit systems. Geostationary is also the highest earth orbit and hence, also provides the greatest visibility using only a few satellites. The coverage region of a satellite is called its footprint. This is the region from which the satellite is visible.
The infographic provides an introduction on how the satellite systems are different based on their orbits. It gives details about the LEO, MEO and GEO satellites. The parameters like satellite height, orbital period, satellite life etc. have been taken into consideration to bring out the differences between them.
