The satellite orbit are used to cover the required application areas.

This means the track of the satellite as seen from the central body will repeat exactly after a fixed number of orbits. Polar orbits are a type of low earth orbit as they are at low altitudes between 200 to 1000 km. These are called as orbits of the satellite. Adapted from fundamentals of space systems by vincent l.

A satellite can move in three types of orbits namely a. Inclined orbit the path along which satellite moves in the space around earth are called orbits. A passive satellite can be further subdivided into two types namely natural satellites and artificial. Russian communications satellites and the sirius radio satellites currently use this type of orbit.

The satellite can be rotated around the earth through different paths. Even a deviation within 20 to 30 degrees is still classed as a polar orbit. Pisacane 2005 the molniya orbit is highly eccentric. Satellites in a polar orbit do not have to pass the north and south pole precisely.

Synchronous orbit it lies in the equatorial plane of the earth. This orbit is most useful orbit for communication purposes. 1975 their high orbits and visible light and infrared sensors allow for constantsurveillance of weather patterns over the entire planet and have enabledgoes to revolutionize the science of weather prediction. In practice only 1 1 ratio geosynchronous and 1 2 ratios semi synchronous are common.

The satellite moves in an extreme ellipse with the earth close to one edge. An orbit whose period is a rational multiple of the average rotational period of the body being orbited and in the same direction of rotation as that body.
