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.

Types of satellites ppt.

Tether satellites are mainly used for altitude control stabilization propulsion maintaining relative positions of a larger spacecraft sensor system and momentum exchange. Low earth orbit leos medium earth orbit meos global positioning system gps geostationary geos applications 3. Orbits are categorized by its altitude inclination with reference to the equatorial plane eccentricity synchronization parameters planet centered pseudo orbit and others. Leo low earth orbit and.

A few space probes have been placed into orbit around other bodies and become artificial satellites to the moon venus mars jupiter and saturn. 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. Three synchronous satellite are placed in such a way to provide 100 earth coverage. Satellites are used for a large number of purposes.

Satellites in high earth orbit require the most energy to reach their destination. 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. Heo highly elliptical orbit geo stationary earth orbit. Types of satellite natural.

Satellites moving close to the earth s surface are ideal for making observations for military purposes and for collecting weather data. The international space station orbiting the earth a. Geo geo stationary earth orbit 2. Satellites overview history launching of satellites how satellites work orbit distance types.

Thousands of unused satellites and satellite fragments orbit the earth as space debris. Such as the moon orbiting around the earth artificial. Types of satellites based on its application are. Meo medium earth orbit 3.

There are different types of tether satellites including skyhooks format flying tethers momentum exchange tethers and electrodynamic tethers. 8 uses of satellites. 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 weigh around 2 500 kgs.

These satellites have almost a distance of 36 000 km to the earth. Types of satellite orbits. Satellites in a highly inclined orbit such as a polar orbit take more energy than a satellite that circles the earth over the equator. They complete exactly one rotation per day.

The geo satellites are at an altitude of 35 768 kms which orbit in equatorial plane with 0 degree inclination. A satellite with a low inclination can use the earth s rotation to help boost it into orbit.
