WORKING OF SATELLITE

Working Of Satellite(Pic Mode)

A satellite works by receiving radio signals sent from the Earth and resending the radio signals back down to the Earth

A modern communications satellite receives the radio signal and sends it back down to Earth stronger than it was received. This process is called "amplification" of the radio signal.

People communicate to a satellite using an antenna on the ground, which called an "earth station" in technical terms. The earth station sends up radio signals to the satellite. These signals are called "uplinks."

Working Of Satellite(Pic Mode)

The satellite receives these signals, makes them stronger, and then re-transmits them back down to the Earth. These signals back to the Earth are called "downlinks."
