Types of satellites based on orbits.

Moons by contrast are not in a heliocentric orbit. An orbit about the center of a galaxy the sun follows this type of orbit about the galactic center of the milky way. The satellite s orbit is a critical component of its function. There are a number of definitions associated with various different types of satellite orbits.

The satellite moves in an extreme ellipse with the earth close to one edge. Using this scheme there are three categories source. Satellite orbits vary greatly depending on the purpose of the satellite and are classified in a number of ways. Satellites moving close to the earth s surface are.

Geostationary orbits also called geosynchronous or synchronous are orbits in which the satellite is always positioned over the same spot on earth many geostationary satellites are above a band along the equator with an altitude of about 22 223 miles or about a tenth of the distance to. Russian communications satellites and the sirius radio satellites currently use this type of orbit. 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. Sun synchronous orbit sso is a particular kind of polar orbit.

There are three basic kinds of orbits depending on the satellite s position relative to earth s surface. Basically there are 3 kinds of satellite orbits which depend on its position relative to the surface of the earth. Low earth orbits leo leo satellites occupy a region of space from about 111 miles 180 kilometers to 1 243 miles 2 000 kilometers above earth. Space foundation editorial team.

Polar orbits are a type of low earth orbit as they are at low altitudes between 200 to 1000 km. Even a deviation within 20 to 30 degrees is still classed as a polar orbit. Satellites can operate by themselves or as part of a larger system a satellite formation or satellite constellation. Pisacane 2005 the molniya orbit is highly eccentric.

Geostationary orbita satellite on a geostationary or geosynchronous orbit stays in the same spot relative to earth. Adapted from fundamentals of space systems by vincent l. The above three are the major three categories of satellites apart from these the satellites are also classified based on the following types of orbits. Well known overlapping classes include low earth orbit polar orbit and geostationary orbit.

1 5 4 sun synchronous orbits satellites. 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. You can also classify satellites based on their height above earth s surface. These satellites rise and set with the sun.
