The Anna University is provides notes for Satellite communication. The Satellite communication is used in telecommunications.

The use of artificial satellites to provide communication links between various points on Earth.

Satellite communications is playing a vital role in the global telecommunications system.

Approximately 2,000 artificial satellites orbiting Earth relay analog and digital signals carrying voice, video, and data to and from one or many locations worldwide.
