SOLAR SYSTEM

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 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-4: -The International Space Station (ISS) is the largest modular space station in low Earth orbit.
