Types Of Satellites Ppt

Satellites in high earth orbit require the most energy to reach their destination.

Types of satellites ppt. Three synchronous satellite are placed in such a way to provide 100 earth coverage. Thousands of unused satellites and satellite fragments orbit the earth as space debris. Hence three such synchronous satellites are required to cover the entire earth. Meo medium earth orbit 3.

Orbits are categorized by its altitude inclination with reference to the equatorial plane eccentricity synchronization parameters planet centered pseudo orbit and others. 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. Tether satellites are mainly used for altitude control stabilization propulsion maintaining relative positions of a larger spacecraft sensor system and momentum exchange. Satellites are used for a large number of purposes.

A few space probes have been placed into orbit around other bodies and become artificial satellites to the moon venus mars jupiter and saturn. Leo low earth orbit and. The geo satellites are at an altitude of 35 768 kms which orbit in equatorial plane with 0 degree inclination. Types of satellite orbits.

Satellites moving close to the earth s surface are ideal for making observations for military purposes and for collecting weather data. Satellites in a highly inclined orbit such as a polar orbit take more energy than a satellite that circles the earth over the equator. Heo highly elliptical orbit geo stationary earth orbit. 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.

They complete exactly one rotation per day. 8 uses of satellites. 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. The international space station orbiting the earth a.

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. There are 4 types of orbits they are. 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. Geo geo stationary earth orbit 2. A satellite with a low inclination can use the earth s rotation to help boost it into orbit. Satellites weigh around 2 500 kgs.

Such as the moon orbiting around the earth artificial. These satellites have almost a distance of 36 000 km to the earth.
