Geo geostationary earth orbit at 36 000 kms above earth s surface.

Types of satellite orbits pdf. Sun synchronous orbit sso is a particular kind of polar orbit. Space foundation editorial team. Meo medium earth orbit or ico intermediate. An orbit around the sun in the solar system all planets comets and asteroids are in such orbits as are many artificial satellites and pieces of space debris.

Heo highly elliptical orbit geo stationary earth orbit. When satellites orbit the earth either in a circular or elliptical orbit the satellite orbit forms a plane that passes through the centre of gravity or geocentre of the earth. Even a deviation within 20 to 30 degrees is still classed as a polar orbit. Leo low earth orbit at 500 1500 kms above earth s surface.

Since there are 365 days in a year and 360 degrees in a circle it means that the satellite has to shift its orbit by approximately one degree per day. There are several types of earth orbit and each offers certain advantages and capabilities. An orbit about the center of a galaxy the sun follows this type of orbit about the galactic center of the milky way. Use of a geostationary orbit is extremely valuable for weather monitoring and communication phones television radio because satellites in this orbit provide a constant view of the same surface.

There are 4 types of orbits they are. Types of satellite systems four different types of satellite orbits have been identified depending on the shape and diameter of each orbit.

Polar orbits are a type of low earth orbit as they are at low altitudes between 200 to 1000 km. The various types of satellite and projectile orbits are described and related to the conditions in terms of energy and angular momentum under which the ideal orbits occur.

These satellites orbit at an altitude between 700 to 800 km.
