here some of the concepts are given below .
There are many kinds of satellites and many ways of building a satellite. Most satellites have similar parts, however. These parts include
(1) radios to talk to people on earth;
(2) rockets to move the satellite in space;
(3) batteries to supply energy; and
(4) computers to control the satellite. Some satellites also have cameras to take pictures from space

DIFFERENT PARTS

• Antennas and transceivers send and receive radio signals to and from the Earth or another satellite;
• Rocket motors move the satellite in space;
• Fuel tanks store the fuel for the rocket;
• Solar panels use solar cells to turn the sun's energy into electricity;
• Batteries store the electricity generated by the solar panels; and.
• On-board processors provide the “brain” of the satellite and tell the satellite to do what humans want it to do
