Types of Satellite Communication System

Satellite communication system uses satellite technology for communications. The services provided by satellite communications are internet, voice and video calling, fax, radio channels, military applications and television.

In satellite communication, transferring of signal between the receiver and sender is done with the help of satellite. The signal is a beam of modulated microwaves sent towards the satellite. Then the signal is amplified by satellite and sent back to the antenna of the receiver present on the earth’s surface.This type of communication is called space communication.

Satellite communications can provide communication capabilities spanning long distances and can operate under conditions which are inoperable for other forms of communication.There are around 2,000 communications satellites present in Earth’s orbit, used by both government and private organizations.

Two types of satellites which are used commonly in satellite communication are active and passive satellites:-

Passive satellites: It is like a plastic balloon with a metal coated over it. This sphere reflects the microwave signals coming from one location of the earth to another one. This is also called passive sphere. Moon is passive satellite of the earth.

Active satellites: It basically amplifies the microwave signals coming. In active satellites a receiver, an antenna system, power supply, transmitter is used. These satellites are also called as transponders. Microwaves are generated by the transmitters fitted on the earth.

These rays are then received by the transponders attached to the satellite. After amplifying, these signals are then transmitted back to earth. This sending can be done at the same time or after some delay. These amplified signals are later stored in the memory of the satellites, when earth faces the satellite. Afterwards satellite sends the signals to earth.

Some active satellites also have recording and programming features. Then these recordings can be easily watched. The signals that come from the satellite are of very low intensity. Their receivers then amplify these signals themselves. After amplification they become available for further use.

Prominent Advantages of Satellite Internet

Progressing from dialup to DSL and cable internet was a big leap in the world of internet connectivity. But thanks to satellite connectivity services, we now have internet on our smartphones. These services are a step ahead into the provision of internet facility to all.

The vast availability and impressive growth models the satellite internet brings with it has many advantages for both home and business usage. Here are some prominent benefits of satellite internet.

Easy Installation

Satellite internet is very easy to install. The technicians can configure your account and install a dish for signal transmission and reception. The dish is directly connected to the computer while facing the southern sky for uninterrupted services.

Worldwide Coverage

Irrespective of where you live, satellite internet can reach you. It just requires a satellite in the geostationary orbit and the signal can reach anywhere on the planet.

Faster Internet

Satellite internet has surpassed high speeds a long time ago even in the rural areas. Download speeds via these connectivity services are about nine times faster as compared to the dial up connections.

Multiple Devices:

While normal internet connections are restricted to one PC, satellite internet can connect multiple devices as well as connect to a hub computer. You can connect your PC, laptops, tablets and smartphones at the same time.

DSL or other services are affected by the unpredictable weather conditions and can go off without warning. They are expensive than satellite internet and can take a long time to reestablish a connection in case there is a fault in the lines. Therefore, satellite connectivity is the better option to choose, for faster and unimpeded connection.
