Antenna Subsystem In Satellite Communication

Satellite antennas perform two types of functions.

Antenna subsystem in satellite communication.

Satellite systems ravikiran s. Satellite control and monitoring is accomplished through monitors and keyboard interface. 1 explain different types of antenna used in satellite communication. Those are space segment and earth segment.

It is one of the most important subsystem of space segment subsystems. Satellite communication system uses a variety of antenna system. May 2013 may 2014 dec 2014. These subsystems include command and mission data handling telemetry and tracking and the antenna payloads for both command telemetry and mission data.

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. Now let us discuss about the satellite antennas. We know that communication refers to the exchange sharing of information between two or more entities through any medium or channel. Satellite communication introduction.

The function of each subsystem and the relationships to the others will be. This maybe linear dipole helix horn antenna array and parabolic reflector. Antennas are present in both satellite and earth station. Among which the main operations are orbit controlling altitude of satellite monitoring and controlling of other subsystems.

Explain with neat diagram the antennas used in satellite communication. Transponder performs the functions of both transmitter and receiver responder in a satellite. 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. In other words it is nothing but sending receiving and processing of.

The tracking system present in the earth station performs mainly two functions. The tracking subsystem keeps track with the satellite and make sure that the beam comes towards it in order to establish the communication. In general terms a satellite is a smaller object that revolves around a larger object in space. Attitude orbit control system ttc m system power system communication subsystems satellite antennas space qualification equipment reliability 3.

The subsystem which provides the connecting link between transmitting and receiving antennas of a satellite is known as transponder. Those are receiving of signals which are coming from earth station and transmitting signals to one or more earth stations based on the requirement. In satellite communication system various operations take place. Those are satellite acquisition and tracking of satellite.

2 explain briefly the offset feed used with paraboloidal reflector antenna stating its main advantages and disadvantages. The antenna subsystem are complicated mechanical assemblies that are folded into dense packet for launch and must be deployed in large accurately alight assembly during orbit.
