Artificial communication satellites

1.

ARTIFICIAL COMMUNICATION
SATELLITES

2.

Artificial communication satellites are placed in an orbit around the
Earth. They relay radio and television signals around the curved
surface of the Earth and thus serve the purpose of intercontinental
radio and television transmission.

3.

As for active satellites, they are used to receive, amplify, and
retransmit signals being sent for the purpose of communication.

4.

The function of passive satellites is only to reflect the transmitted
signals from the surface of the Earth.
