Components of a Communications Satellite
Communication Antenna
The entenna transmits and receives the modulated carrier signal at the radio frequency (RF) portion of the electromagnetic spectrum.

Solar Cells
These cells have a moderate initial efficiency and are made very blue-sensitive, since the response to short wavelength light is considerably more resistant to radiation than the response to long wavelength light.

Batteries
The batteries are designed and manufactured with the storage capacity required to power the satellite during eclipse with additional margin to account for potential emergencies.

Radio receivers and trasmitters
A radio receiver is the opposite of a radio transmitter. It uses an antenna to capture radio waves, processes those waves to extract only those waves that are vibrating at the desired frequency, extracts the audio signals that were added to those waves, amplifies the audio signals, and finally plays them on a speaker.

Rocket Fuel
Satellites do carry their own fuel supply, but unlike how a car uses gas, it is not needed to maintain speed for orbit. It is reserved for changing orbit or avoiding collision with debris.

Thrusters
A thruster is a propulsive device used by spacecraft for station keeping, attitude control, in the reaction control system, or long-duration, low-thrust acceleration.

Camera
A typical video surveillance solution over satellite is made up of a camera connected to a video encoder and either a BGAN or VSAT terminal via Ethernet or WiFi, normally in an unmanned or semi-manned location. The camera sends a JPEG image or motion video clip to a specified location when it detects a motion.
