Satellite Orbits And Its Types

Satellite s velocity the speed it is travelling in a straight line force of the earth s gravitational pull on the satellite an artificial satellite is always falling towards earth but it has enough tangential.

Satellite orbits and its types. Many geostationary satellites are above a band along the equator. There are several types of earth orbit and each offers certain advantages and capabilities. In practice only 1 1 ratio geosynchronous and 1 2 ratios semi synchronous are common. This means the track of the satellite as seen from the central body will repeat exactly after a fixed number of orbits.

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. Geostationary orbits also called geosynchronous or synchronous are orbits in which the satellite is always positioned over the same spot on earth. 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. These orbits allows a satellite to pass over a section of the earth at the same time of day.

There are three basic kinds of orbits depending on the satellite s position relative to earth s surface. On 4 october 1957 the soviet union launched the world s first artificial satellite sputnik 1 since then about 8 900 satellites from more than 40 countries have been launched. If a satellite orbits from the north pole geographic not magnetic to the south pole its inclination is 90 degrees. Upon launch a satellite or spacecraft is most often placed in one of several particular orbits around earth or it might be sent on an interplanetary journey meaning that it does not orbit earth anymore but instead orbits the sun until its arrival at its final destination like mars or jupiter.

Each will have its own type of orbit depending upon its application. In the context of spaceflight a satellite is an object that has been intentionally placed into orbit these objects are called artificial satellites to distinguish them from natural satellites such as earth s moon. Space foundation editorial team. 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.

Orbital inclination is the angle between the plane of an orbit and the equator. Types of satellite orbits. Also the new cubesats or cube satellites use relatively low orbits as well in view of te power levels they can transmit and the allowable path losses.
