Technology has advanced to such an extent, that value of time has become priceless. Satellite technology system has completely erased the gap between time and communication. Telecommunication has witnessed the use of satellite communication system to its worldwide accessibility and reaching the never known ends of the earth. Satellites have done an incredible job.

1. Satellite Communication
A Boon for Communication
What is should be best known about a Satellite? It is a self-contained
communication system that enables the reception of signals from Earth and their
retransmit, back via a transponder (receiver and transmitter of radio signals).
Satellites are a medium for communication, the very purpose for which they are
developed.
Today communication has become much faster (fraction of seconds) and efficient
with the growing satellite communication services. Both the wireless and mobile
communication has remarkably proved to be a growing industry. Satellite
communication system plays a pivotal role in the telecommunication industry.
The under developed countries are also treading the path of rising technological
know-how in terms of telecommunication, especially by the use of mobile
communication.
Telecommunication Made Easy
In telecommunications, satellite communication technology facilitates the use of
artificial satellite that provides links for communication among various parts of
Earth. It is indeed incredible that the development of satellite communication
technology has set the paths for establishing a global communications satellite
industry as well.
Did you know that, there are around 2,000 artificial satellites orbiting the Earth?
These artificial satellites relay both analog and digital signals. They carry voice,
video and data to and fro from one or more locations across the globe.
Satellite communication technology serves the best solution even to reach out to
the remotest portions of the earth. The wireless and wire line communication are
way behind to score on what Satellite technology can do. Geographical
boundaries are no more an excuse as the satellite communication technology can
access any network.

2. Unit of Measurement
A powerful satellite is one which has a strong combination of bandwidth and
power. This determines the capacity of the satellite. The unit of measurement is
Hertz (cycles per second) MegaHertz (MHz) or KiloHertz (kHz) large bandwidths.
Types of Satellite Communication
There are different types of satellite communication system, depending upon the
type of satellite and the signal being used.
Passive Communication
The satellite receives radio signals and reflects back to another location on
the earth. This system is capable of multiple accesses as it uses very wide
bandwidths.
Active Communication
The satellite receives radio signals and amplifies these signals before
transmitting back to earth, thereby functions as a repeater. The ‘up-link’
terminal on earth transmits the radio signals to the satellite. The satellite
amplifies the signals, transmits back through the ‘down-link’ to the terminal
or other terminals. This system supports multiple links at one time or
transmission of signals to more than one terminal.
Multi-Beam Communication
The spatial division multiple access technology under this system allows
different directional antennas in a satellite to operate on different radio
frequencies. This is a cost effective satellite communication system.
Global Positioning System
This is based on the location or position of the person or place on the
globe. Commonly known as the GPS, it basically determines the position

3. through the use of positional data and timing signals via many different
satellites.
Satellite Communication System
It has become a blessing to mankind for the numerous purposes it serves.
Communication is now just a matter of fraction of seconds.
