What are the basic concept of satellite communications?

Satellite communications involves four steps: An uplink Earth station or other ground equipment transmits the desired signal to the satellite. The satellite amplifies the incoming signal and changes the frequency. The satellite transmits the signal back to Earth.

Which communication is used in satellite?

Satellite communications tend to use high frequency signals: Ultra High Frequency (UHF), 300 MHz – 3 GHz and Super High Frequency (SHF), 3 – 30 GHz.

What are the advantages of satellite communication?

Satellite Communication – Advantages

  • Flexibility.
  • Ease in putting in new circuits.
  • Distances are effortlessly taken care of and expense doesn’t make a difference.
  • Broadcasting conceivable outcomes.
  • Each and each side of the earth is secured.
  • User can control the system.

What are types of satellites?

There are two different types of satellites – natural and man-made. Examples of natural satellites are the Earth and Moon. The Earth rotates around the Sun and the Moon rotates around the Earth. A man-made satellite is a machine that is launched into space and orbits around a body in space.

What are satellites used for?

Satellites provide in-flight phone communications on airplanes, and are often the main conduit of voice communication for rural areas and areas where phone lines are damaged after a disaster. Satellites also provide the primary timing source for cell phones and pagers.

What is Satellite Communication What are its uses?

Communications satellites are used for television, telephone, radio, internet, and military applications. The purpose of communications satellites is to relay the signal around the curve of the Earth allowing communication between widely separated geographical points.

What are the applications of satellite communication?


  • Telecommunication.
  • Tele-Medicine.
  • Tele-Education.
  • Mobile Satellite Services.
  • Radio Networking.
  • Village Resource Centre.
  • Satellite Aided Search and Rescue.
  • Satellite Navigation Programme.

How is satellite communication used in wireless communication?

A communication satellite is a microwave repeater station in a space that is used for telecommunication, radio and television signals. A communication satellite processes the data coming from one earth station and it converts the data into another form and send it to the second earth station.

What is satellite communication in IoT?

Wireless data transmission systems are being increasingly deployed in industrial and home automation applications. These robust systems are used to transmit sensor data and control information across network infrastructures.

How is satellite communication used in the world?

Satellite communication is the communication between any two communications earth stations through a satellite. In this communication, electromagnetic waves are used as carrier signals. These signals carry information such as voice, audio, or any other data between ground and space and vice-versa.

How big is the global satellite communication market?

The market is projected to grow from USD 25.33 billion in 2021 to USD 46.50 billion in 2028 at a CAGR of 9.07% in the 2021-2028 period. Satellite communication is the communication between any two communications earth stations through a satellite. In this communication, electromagnetic waves are used as carrier signals.

What are the components of a satellite communications system?

Satellite communications are comprised of 2 main components: The satellite itself is also known as the space segment, and is composed of three separate units, namely the fuel system, the satellite and telemetry controls, and the transponder.

How are satellites used in the maritime industry?

In the maritime community, satellite communication systems such as Inmarsat provide good communication links to ships at sea. These links use a VSAT type device to connect to geosynchronous satellites, which in turn link the ship to a land based point of presence to the respective nations telecommunications system.
