Satellite communication involves the use of artificial satellites to facilitate communication between various points on Earth. This technology allows for long-distance communication, broadcasting, and data transmission by transmitting signals from a ground station to a satellite in orbit, which then relays the signal back down to another ground station. Satellite communication is often used for broadcasting television signals, internet services, global positioning systems (GPS), and military communications. It offers advantages such as wide coverage area, high reliability, and the ability to reach remote or mobile locations. Advances in satellite technology have led to the development of more efficient and high-speed communication systems, making satellite communication an important tool for many industries and applications.
