Leo low earth orbit and.

Types of satellites ppt.

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. 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. Tether satellites are mainly used for altitude control stabilization propulsion maintaining relative positions of a larger spacecraft sensor system and momentum exchange. Three synchronous satellite are placed in such a way to provide 100 earth coverage.

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 low earth orbit leo a low earth orbit leo is as the name suggests an orbit that is relatively close to earth s surface. Satellites overview history launching of satellites how satellites work orbit distance types. Satellites weigh around 2 500 kgs.

Satellites moving close to the earth s surface are ideal for making observations for military purposes and for collecting weather data. 8 uses of satellites. There are different types of tether satellites including skyhooks format flying tethers momentum exchange tethers and electrodynamic tethers. Meo medium earth orbit 3.

Heo highly elliptical orbit geo stationary earth orbit. Types of satellite orbits. Thousands of unused satellites and satellite fragments orbit the earth as space debris. Satellites are used for a large number of purposes.

Types of satellites based on its application are. These satellites have almost a distance of 36 000 km to the earth. The geo satellites are at an altitude of 35 768 kms which orbit in equatorial plane with 0 degree inclination. Satellites can be classified based on their applications orbit in which they are placed.

A satellite with a low inclination can use the earth s rotation to help boost it into orbit. They complete exactly one rotation per day. The international space station orbiting the earth a. Hence three such synchronous satellites are required to cover the entire earth.

Geo geo stationary earth orbit 2. Satellites in high earth orbit require the most energy to reach their destination. Types of satellite natural. There are 4 types of orbits they are.

A few space probes have been placed into orbit around other bodies and become artificial satellites to the moon venus mars jupiter and saturn. Such as the moon orbiting around the earth artificial.
