Types Of Satellites Based On Orbits
Basically there are 3 kinds of satellite orbits which depend on its position relative to the surface of the earth.
Types of satellites based on orbits. The satellite s orbit is a critical component of its function. Satellites can operate by themselves or as part of a larger system a satellite formation or satellite constellation. 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. Polar orbits are a type of low earth orbit as they are at low altitudes between 200 to 1000 km.
Sun synchronous orbit sso is a particular kind of polar orbit. These satellites rise and set with the sun. There are three basic kinds of orbits depending on the satellite s position relative to earth s surface. Space foundation editorial team.
Well known overlapping classes include low earth orbit polar orbit and geostationary orbit. Satellites in a polar orbit do not have to pass the north and south pole precisely. There are several types of earth orbit and each offers certain advantages and capabilities. 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.
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. 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. 1 5 4 sun synchronous orbits satellites.
Satellites moving close to the earth s surface are. Adapted from fundamentals of space systems by vincent l. It flies at an altitude ofread more. Russian communications satellites and the sirius radio satellites currently use this type of orbit.
The satellite moves in an extreme ellipse with the earth close to one edge. You can also classify satellites based on their height above earth s surface. 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. Satellite orbits vary greatly depending on the purpose of the satellite and are classified in a number of ways.
Geostationary orbita satellite on a geostationary or geosynchronous orbit stays in the same spot relative to earth. There are a number of definitions associated with various different types of satellite orbits. Pisacane 2005 the molniya orbit is highly eccentric. Using this scheme there are three categories source.
