Angle Period In Satellite Communication

A geostationary orbit also referred to as a geosynchronous equatorial orbit geo is a circular geosynchronous orbit 35 786 kilometres 22 236 miles above earth s equator and following the direction of earth s rotation.

Angle period in satellite communication. Orbits with 0 inclination are generally called equatorial orbits. For example moon is a natural satellite of earth. The communication satellites in this orbit operates at a distance of about 500 to 1200 km above the earth s surface and their orbital time period generally ranges between 95 to 120 minutes. In other words it is nothing but sending receiving and processing of.

Satellite communication introduction. In general terms a satellite is a smaller object that revolves around a larger object in space. Kepler s laws for orbits. He has already pointed out that a satellite in a circular equatorial orbit with a radius of about 42 242 km wound have an angular velocity that matched the.

Multiple choice questions and answers on satellite communication. Multiple choice questions and answers on satellite communication. A communications satellite is an artificial satellite that relays and amplifies radio telecommunications signals via a transponder. It creates a communication channel between a source transmitter and a receiver at different locations on earth communications satellites are used for television telephone radio internet and military applications.

Without gravity the satellite s inertia would carry it off into space. Orbital velocity is the velocity needed to achieve balance between gravity s pull on the satellite and the inertia of the satellite s motion the satellite s tendency to keep going. Another definition of inclination is the angle between the equatorial plane and the satellite orbital plane as the satellite enters the northern hemisphere. Has the same period a that of the earth b.

Basic geodetic theory is applied to determine the azimuth and geodetic altitude required to point dish antennas to geostationary communi. When the angle of inclination is 0 the satellite is directly above the equator. Determination of look angles to geostationary communication satellites by tom is soler 1 member asce and david w. There are about 2 000 communications satellites.

The intelsat iv satellite launched in 1974 had two earth coverage antenna and two narrower angle antennas. A big role is played by satellite communication for this advancement the idea of satellite communication was first introduced by a british science friction writer authur c. We know that communication refers to the exchange sharing of information between two or more entities through any medium or channel. The higher the satellite the longer the period of its orbit so moving it high enough will make its orbit match earth s rotation rate 3 2 e 2 t r gm π 42 166 km so altitude above surface 35 788 km where t 86 164 1 s sidereal day the period of earth s rotation with respect to the stars.
