Different Types Of Satellites Ppt

Such objects are sometimes called artificial satellites to distinguish them from natural satellites.

Different types of satellites ppt.

Types of satellite systems four different types of satellite orbits have been identified depending on the shape and diameter of each orbit. Since the 1960s more than 26 000 satellites have been launched for both military and civilian purposes. Types of satellite systems. As a result the receiver generally needs to see at least 4 satellites to calculate the 4 unknowns.

There are many different types of satellites in the sky and they have a variety of uses from transmissions to data gathering. 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. Just as different seats in a theater provide different perspectives on a performance different earth orbits give satellites varying perspectives each valuable for different reasons. The receiver then does some math and calculates its location on the earth.

Four different types of satellites orbits have been identified. Satellite dishes come in different models and sizes. Leo low earth orbit at 500 1500 kms above earth s surface. Different types of satellite dishes 1 different types of satellite dishes 2 one of the important technologies and equipment used in transmitting and receiving audio and video signals the automatic satellite dish is a useful and sophisticated kind of microwave and parabolic antenna.

The receiver calculates 4 parameters. Meo medium earth orbit or ico intermediate. Orbital heights satellite geostationary and geosynchronous geo a satellite is an artificial object which has been intentionally placed into orbit. Some seem to hover over a single spot providing a constant view of one face of the earth while others circle the planet zipping over many different places in a.

Geo geostationary earth orbit at 36 000 kms above earth s surface. 63 of current operational satellites are at a low orbit level 2000 km 6 are at medium orbit level 20000 km 20 are at the geostationary orbit level 36000 km and rest 2 at elliptic level 36000 km. Satellites are a manmade construction which are launched into orbiting patterns in space. The more satellites the receiver can track the more accurate the location calculation.

Tether satellites are mainly used for altitude control stabilization propulsion maintaining relative positions of a larger spacecraft sensor system and momentum exchange. Geo geostationary earth orbit at about 36 000km above the earth s surface. There are different types of tether satellites including skyhooks format flying tethers momentum exchange tethers and electrodynamic tethers. Satellites moving close to the earth s surface are ideal for making observations for military purposes and for collecting weather data.
