What are subsystems in satellite communication?
A satellite communication consists of mainly two segments. Those are space segment and earth segment. So, accordingly there will be two types of subsystems namely, space segment subsystems and earth segment subsystems.
What is satellite communication with diagram?
A communication satellite is an artificial satellite that transmits the signal via a transponder by creating a channel between the transmitter and the receiver located at different locations on the Earth. Telephone, radio, television, internet, and military applications use satellite communications.
What are the subsystems of a satellite?
A Complete Satellite consists of several subsystems, but the most important of them are as follow:
- Power Supply System.
- Attitude and Orbit Control System.
- Telemetry, Tracking and Command System.
- Communication Subsystem.
Why transponders is the most important subsystem of space segment subsystems?
The subsystem, which provides the connecting link between transmitting and receiving antennas of a satellite is known as Transponder. 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.
Which satellite subsystem is used in monitoring the status of other subsystems?
Tracking Subsystem Satellite Control Center (SCC) monitors the working and status of space segment subsystems with the help of telemetry downlink. And, it controls those subsystems using command uplink. We know that the tracking subsystem is also present in an earth station.
What is block diagram of communication system?
The block diagram of a communication system will have five blocks, including the information source, transmitter, channel, receiver and destination blocks. The information source converts this information into physical quantity.
What is terrestrial communication?
A terrestrial communication system, facilitating audio, video, data, and any other type of communication within a local geographical area, and with an extremely large number of communication channels being made available simultaneously at a very low cost.
What are communication subsystems?
The communications subsystem is responsible for ensuring telecommunication between the satellite and another system, which may be either another satellite or a ground station. The communications subsystem receives and demodulates uplink signals and modulates and transmits downlink signals.
