Types of satellite orbits.

Types of satellites ppt.

These satellites have almost a distance of 36 000 km to the earth. Leo low earth orbit and. There are different types of tether satellites including skyhooks format flying tethers momentum exchange tethers and electrodynamic tethers. Geo geo stationary earth orbit 2.

The geo satellites are at an altitude of 35 768 kms which orbit in equatorial plane with 0 degree inclination. Satellites in high earth orbit require the most energy to reach their destination. Hence three such synchronous satellites are required to cover the entire earth. They complete exactly one rotation per day.

Types of satellite natural. Satellites are used for a large number of purposes. The antennas are at fixed positions and use an uplink band of 1 634 5 1 660 5 mhz and downlink in the range of 1 530 1 559 mhz. Satellites in a highly inclined orbit such as a polar orbit take more energy than a satellite that circles the earth over the equator.

Satellites weigh around 2 500 kgs. It is normally at an altitude of less than 1000 km but could be as low as 160 km above earth which is low compared to other orbits but still very far above earth s surface. Satellites overview history launching of satellites how satellites work orbit distance types. Low earth orbit low earth orbit leo a low earth orbit leo is as the name suggests an orbit that is relatively close to earth s surface.

Types of satellites based on its application are. Geosynchronous orbits geo geo satellites orbit earth at an altitude greater than 22 223 miles 36 000 kilometers and their orbital period is the same as earth s rotational period. Such as the moon orbiting around the earth artificial. Heo highly elliptical orbit geo stationary earth orbit.

Three synchronous satellite are placed in such a way to provide 100 earth coverage. Meo medium earth orbit 3. A few space probes have been placed into orbit around other bodies and become artificial satellites to the moon venus mars jupiter and saturn. Tether satellites are mainly used for altitude control stabilization propulsion maintaining relative positions of a larger spacecraft sensor system and momentum exchange.

A satellite with a low inclination can use the earth s rotation to help boost it into orbit. The international space station orbiting the earth a. Orbits are categorized by its altitude inclination with reference to the equatorial plane eccentricity synchronization parameters planet centered pseudo orbit and others. Low earth orbit leos medium earth orbit meos global positioning system gps geostationary geos applications 3.

Satellites can be classified based on their applications orbit in which they are placed. There are 4 types of orbits they are.
