Satellite communications is a technology that uses satellites in orbit around the Earth to transmit and receive signals. These signals can carry various types of information, including voice, video, and data, allowing for communication over long distances. Satellites act as relay stations, receiving signals from one location and sending them to another, making global communication possible. The system consists of three main components: satellites, ground stations, and user terminals. Satellites are placed in different orbits, such as geostationary or low Earth orbit, to optimize coverage and performance. Ground stations are equipped with antennas to send and receive signals, while user terminals, like satellite phones or dishes, allow individuals and businesses to connect to the satellite network.
