Satellite communications involve the use of artificial satellites to send and receive signals for various forms of communication, such as television, internet, and phone services. These satellites orbit the Earth and act as relay stations, transmitting data between ground stations and users. This technology allows people to connect over long distances, even in remote areas where traditional communication methods may not be available. The process begins when a signal is sent from a ground station to a satellite in space. The satellite then amplifies and retransmits the signal back to another ground station or directly to a user's device. This system is crucial for global connectivity, enabling services like GPS, satellite TV, and emergency communications.
