The tracking subsystem keeps track with the satellite and make sure that the beam comes towards it in order to establish the communication.
Antenna subsystem in satellite communication.
A satellite communication consists of mainly two segments.
Those are receiving of signals which are coming from earth station and transmitting signals to one or more earth stations based on the requirement.
Attitude orbit control system ttc m system power system communication subsystems satellite antennas space qualification equipment reliability 3.
In satellite communication system various operations take place.
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.
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 satellite acquisition and tracking of satellite.
1 explain different types of antenna used in satellite communication.
The subsystem which provides the connecting link between transmitting and receiving antennas of a satellite is known as transponder.
Satellite control and monitoring is accomplished through monitors and keyboard interface.
The tracking system present in the earth station performs mainly two functions.
In other words it is nothing but sending receiving and processing of.
Among which the main operations are orbit controlling altitude of satellite monitoring and controlling of other subsystems.
Those are space segment and earth segment.
Satellite antennas perform two types of functions.
Antennas are present in both satellite and earth station.

Satellite communication introduction.
In general terms a satellite is a smaller object that revolves around a larger object in space.
The function of each subsystem and the relationships to the others will be.
We know that communication refers to the exchange sharing of information between two or more entities through any medium or channel.
This maybe linear dipole helix horn antenna array and parabolic reflector.
For example moon is a natural satellite of earth.
This tracking can be done in one of the.
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.
Satellite communication system uses a variety of antenna system.
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.
It is one of the most important subsystem of space segment subsystems.
