Antenna Subsystem In Satellite Communication

In satellite communication system various operations take place.

Antenna subsystem in satellite communication.

A satellite communication consists of mainly two segments. Satellite systems ravikiran s. In general terms a satellite is a smaller object that revolves around a larger object in space. This maybe linear dipole helix horn antenna array and parabolic reflector.

Satellite communication introduction. 1 explain different types of antenna used in satellite communication. For example moon is a natural satellite of earth. Those are receiving of signals which are coming from earth station and transmitting signals to one or more earth stations based on the requirement.

Transponder performs the functions of both transmitter and receiver responder in a satellite. Now let us discuss about the satellite antennas. This tracking can be done in one of the. Satellite control and monitoring is accomplished through monitors and keyboard interface.

The function of each subsystem and the relationships to the others will be. Attitude orbit control system ttc m system power system communication subsystems satellite antennas space qualification equipment reliability 3. It is one of the most important subsystem of space segment subsystems. Explain with neat diagram the antennas used in satellite communication.

Satellite antennas perform two types of functions. We know that communication refers to the exchange sharing of information between two or more entities through any medium or channel. The tracking system present in the earth station performs mainly two functions. The objective of this chapter is to provide a comprehensive end to end overview of existing communication subsystems residing on both the satellite bus and payloads.

May 2013 may 2014 dec 2014. Satellite communication system uses a variety of antenna system. The tracking subsystem keeps track with the satellite and make sure that the beam comes towards it in order to establish the communication. Those are space segment and earth segment.

Those are satellite acquisition and tracking of satellite. In other words it is nothing but sending receiving and processing of. 2 explain briefly the offset feed used with paraboloidal reflector antenna stating its main advantages and disadvantages. Antennas are present in both satellite and earth station.

For the satellite and ground facility for a communications satellite application the elements on the ground include the ttc m antenna telemetry receiver command transmitter tracking subsystem and associated processing and analysis functions. These subsystems include command and mission data handling telemetry and tracking and the antenna payloads for both command telemetry and mission data.
