Types Of Satellite Orbits Pdf

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

Types of satellite orbits pdf.

Geo geostationary earth orbit at 36 000 kms above earth s surface. Even a deviation within 20 to 30 degrees is still classed as a polar orbit. Heo highly elliptical orbit geo stationary earth orbit. This is because the satellite orbits at the same speed that the earth is turning it is always directly over the same place on the earth s surface.

These orbits allows a satellite to pass over a section of the earth at the same time of day. The satellite moves in an extreme ellipse with the earth close to one edge. 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. Moons by contrast are not in a heliocentric orbit.

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. There are several types of earth orbit and each offers certain advantages and capabilities. 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. Meo medium earth orbit or ico intermediate.

Satellites in a polar orbit do not have to pass the north and south pole precisely. Sun synchronous orbit sso is a particular kind of polar orbit. Meo medium earth orbit 3. Polar orbits are a type of low earth orbit as they are at low altitudes between 200 to 1000 km.

An orbit about the center of a galaxy the sun follows this type of orbit about the galactic center of the milky way. Pisacane 2005 the molniya orbit is highly eccentric. 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. Types of satellite orbits.

Adapted from fundamentals of space systems by vincent l. Low earth orbit leo leo is commonly used for communication and remote sensing satellite systems as well as the international space station iss and hubble space telescope. Leo low earth orbit at 500 1500 kms above earth s surface. 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.

Leo low earth orbit and. Types of satellite systems four different types of satellite orbits have been identified depending on the shape and diameter of each orbit. These satellites have almost a distance of 36 000 km to the earth. There are 4 types of orbits they are.
