What issatellite communications

Satellite communications refer to the use of orbiting radio relay stations to receive, amplify and transmit analogue and digital communications that are carried inside a carrier frequency.

Types of Satellites

There are three classifications for satellites based on their distance from the earth: GEO, LEO, and MEO.

  • The geostationary satellites or GEO, are about 22,282 miles above the earth and appear stationary to an observer on the ground since they rotate with the earth.
  • The low-earth orbit (LEO) and medium-earth orbit (MEO) satellites orbit the Earth at much closer ranges.

Applications of Satellite Communications

Satellite services can be used for both fixed and mobile (FSS/MSS) communication. They can deliver signals to mobile terminals such as vehicles, ships, and planes, as well as permanent terminals such as rooftop dishes, also known as FSS.

Benefits of Satellite Communications

Satellite communications offer several benefits:

  • They cover a large area, often making them ideal for remote, rural areas where there’s no fixed or wireless connectivity.
  • They provide an alternative to terrestrial communication, especially in situations such as natural disasters when land-based infrastructure is unavailable, damaged, or destroyed.
  • They’re secure and reliable, making them suitable for military and government use, as well as commercial applications such as banking and finance, aviation, and logistics.


Satellite communications have become an integral aspect of modern communication technologies. They offer a reliable and efficient alternative to traditional land-based connectivity and can be used in a variety of applications and industries.


What is a Satellite?

A satellite is a radio relay station that orbits the earth and receives, amplifies and transmits analogue and digital communications that are carried inside a carrier frequency.

What are the different types of Satellites?

There are three classifications for satellites: GEO, LEO, and MEO. GEO satellites are stationary, and LEO and MEO satellites orbit the Earth at much closer ranges.
