Let us learn about Communication Satellite ..

Do you know what is communication satellite?Some people have been heard about this but they did not realize in daily life.So today, I want to share something information that very important in our life. Communication satellite is a satellite that has been stationed in space for the purpose of providing telecommunication.It is commonly used for mobile phone signal,weather tracking or broadcasting television programs.When you make a a long distance phone call, use a cellular phone, a fax machine or listen to radio we are probably used communication satellite,whether directly or indirectly. Furthermore, communication satellite allow radio,television and telephone transmission to be sent live anywhere in the world. Before satellites transmission were difficult or impossible at long distance. The signals which travel in straight lines,could not bend around the Earth to reach destination far away because satellite in orbit, the signals can be sent directly into space and then redirected to another satellite.

The satellite can have a passive role in communication like bouncing signals from the Earth back to another location on the Earth.On the other hand,some satellite carry electronic devices called transponders for receiving, amplifying, and rebroadcasting signals to the Earth.
