Antenna Subsystem In Satellite Communication

This tracking can be done in one of the.

Antenna subsystem in satellite communication.

Satellite antennas perform two types of functions. It is one of the most important subsystem of space segment subsystems. Transponder performs the functions of both transmitter and receiver responder in a satellite. Satellite communication system uses a variety of antenna system.

1 explain different types of antenna used in satellite communication. 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. Those are space segment and earth segment. The tracking system present in the earth station performs mainly two functions.

Satellite control and monitoring is accomplished through monitors and keyboard interface. This maybe linear dipole helix horn antenna array and parabolic reflector. 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. Among which the main operations are orbit controlling altitude of satellite monitoring and controlling of other subsystems.

A satellite communication consists of mainly two segments. May 2013 may 2014 dec 2014. Satellite communication introduction. Satellite systems ravikiran s.

Explain with neat diagram the antennas used in satellite communication. 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. Those are receiving of signals which are coming from earth station and transmitting signals to one or more earth stations based on the requirement. For example moon is a natural satellite of earth.

The subsystem which provides the connecting link between transmitting and receiving antennas of a satellite is known as transponder. Attitude orbit control system ttc m system power system communication subsystems satellite antennas space qualification equipment reliability 3. The function of each subsystem and the relationships to the others will be. Antennas are present in both satellite and earth station.

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 satellite acquisition and tracking of satellite. In other words it is nothing but sending receiving and processing of. We know that communication refers to the exchange sharing of information between two or more entities through any medium or channel.

These subsystems include command and mission data handling telemetry and tracking and the antenna payloads for both command telemetry and mission data. Now let us discuss about the satellite antennas.
