What is the range of satellite communication?
Satellite communications use the very high-frequency range of 1–50 gigahertz (GHz; 1 gigahertz = 1,000,000,000 hertz) to transmit and receive signals. The frequency ranges or bands are identified by letters: (in order from low to high frequency) L-, S-, C-, X-, Ku-, Ka-, and V-bands.
What are the elements of satellite communication system and explain it?
The main components of a satellite consist of the communications system, which includes the antennas and transponders that receive and retransmit signals, the power system, which includes the solar panels that provide power, and the propulsion system, which includes the rockets that propel the satellite.
Which part of the electromagnetic spectrum is used in satellite communication?
Radio waves are used for satellite communication.
What are the reasons to choose 6 4 GHz for satellite communication?
Advantages of 6/4 GHz
- In this band there is no absorption by the rain.
- It has fewest propagation problems.
- There is no change of polarization when the waves pass through the ionosphere.
- RF Components for these bands were being used for terrestrial relay links also and hence they are easily available.
What’s new in the 6th edition of satellite communications systems?
The revised and updated sixth edition of Satellite Communications Systems contains information on the most recent advances related to satellite communications systems, technologies, network architectures and new requirements of services and applications.
What is a satellite communications system?
A satellite communications (satcom) system maybe looked at as comprising of three parts “space segment”, the “ground segment” and the transmission medium ( the space between the Earth and the satellite) The Space Segment1/6 • A telecommunications satellite comprises:
