Definition of satellite:

A satellite is a body that orbits a planet, star, or moon. For instance, the fact that Earth orbits the sun makes it a satellite. The moon is a satellite as well because it revolves around Earth. The term “satellite” typically refers to a device that is launched into space and orbits the Earth or another celestial body.

Satellite communication:

Using a communication satellite in orbit around the Earth, satellite communication is the transfer of information from one location to another. An artificial satellite called a communication satellite establishes a channel between a transmitter and a receiver at various points on Earth in order to transmit a signal using a transponder.
Satellite communications are used in telephone, radio, television, internet, and military applications.

Types of satellite communication:

There are various types of satellite communication, depending on the service offered. Mainly there are three types of satellite communication services are there.

1.Fixed satellite communication services

2.Mobile satellite communication services.

3.Broadcast communication services.

1.Fixed satellite communication services:

Fixed Satellite Services (FSS), which receive and broadcast satellite signals using ground-based equipment at predetermined locations. Most of our domestic and international services, including private business networks and global internet connection, are supported by FSS satellites.

2.Mobile satellite communication services:

Mobile satellite services (MSS) offer two-way voice and data communications to people all over the world who are travelling or residing in remote areas; terminals come in a variety of sizes, including handheld and laptop-sized devices. Moreover, terminals positioned inside of a moving vehicle can continue connections.

3.Broadcast satellite communication services:

Using broadcast signals transferred to and from communication satellites, satellite broadcasting is a method of distributing content. Satellite dishes, also known as parabolic antennae, are used to receive the broadcast signals. The signals are then conditionally sent through a low-noise block converter.

How satellite communication works:

The communication satellites are comparable to the space mirrors that assist in bouncing communications from one side of the globe to the other, including radio, internet data, and television. There are three steps that are necessary to understand how satellite communications function. Which are:




Have a look at a television signal as an example. The first stage begins with the ground station on Earth beaming the signal from the television broadcast on the other side of the planet up to the satellite. Uplink is the term for this procedure. Transponders such radio receivers, transmitters, and amplifiers are used in the second stage. These transponders modify the frequency of the incoming signal and amplify it in order to prevent interference with the outgoing signal. In light of the upcoming signal sources.The data is transmitted through a downlink in the final step to the receiver’s opposite end on earth. It is crucial to realise that there is typically just one uplink and many downlinks.

Advantages of satellite communication:

1.Each and every side of the earth can be covered.

2.New circuits can be easily installed.

3.Since satellites are powered by solar energy, energy is conserved.

4.The system can be managed by users.

Disadvantages of satellite communication:

1.Initial cost is very expensive.

2. due to the interference of frequencies communication services may be disrupted.

3. Interference and expansion.

Applications of satellite communication:




4.Digital cinema.

5.Internet access.
