Antenna subsystem in satellite communication.
These subsystems include command and mission data handling telemetry and tracking and the antenna payloads for both command telemetry and mission data.
In satellite communication system various operations take place.
This maybe linear dipole helix horn antenna array and parabolic reflector.
Those are satellite acquisition and tracking of satellite.
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.
The tracking system present in the earth station performs mainly two functions.
Satellite antennas perform two types of functions.
Satellite communication introduction.
A satellite communication consists of mainly two segments.
Antennas are present in both satellite and earth station.
Explain with neat diagram the antennas used in satellite communication.
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.
We know that communication refers to the exchange sharing of information between two or more entities through any medium or channel.
Transponder performs the functions of both transmitter and receiver responder in a satellite.
In other words it is nothing but sending receiving and processing of.
1 explain different types of antenna used in satellite communication.
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 general terms a satellite is a smaller object that revolves around a larger object in space.
Among which the main operations are orbit controlling altitude of satellite monitoring and controlling of other subsystems.
The function of each subsystem and the relationships to the others will be.
For example moon is a natural satellite of earth.
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.
Those are space segment and earth segment.
Satellite systems ravikiran s.
It is one of the most important subsystem of space segment subsystems.
Satellite control and monitoring is accomplished through monitors and keyboard interface.
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.
