Detailed explanation-1: -Communications satellites are used to send and receive radio signals for television, phone or internet communications. Large concave reflectors called satellite dishes are normally used to send and receive these signals.

Detailed explanation-2: -A satellite is basically a self-contained communications system with the ability to receive signals from Earth and to retransmit those signals back with the use of a transponder-an integrated receiver and transmitter of radio signals.

Detailed explanation-3: -Satellites are used for broadcasting applications, including sending radio and television signals to consumers. The International Space Station is a satellite that provides many services, including research and development, Earth and space observation among other applications.

Detailed explanation-4: -Satellites communicate by using radio waves to send signals to the antennas on the Earth. The antennas then capture those signals and process the information coming from those signals.

Detailed explanation-5: -A satellite is a space station that is designed to orbit the Earth and provide a remote radio signal relaying station for the purpose of extending the range of communications worldwide. From: Electronics Explained, 2010.
