Satellite links are communication pathways that connect ground stations to satellites orbiting the Earth. These links enable the transmission of data, voice, and video signals over long distances, making global communication possible. They are essential for services like television broadcasting, internet access, and weather monitoring. The technology behind satellite links involves radio waves that travel between the ground and the satellite. When a signal is sent from a ground station, it is transmitted to the satellite, which then relays the signal back to another ground station. This process allows for real-time communication across vast areas, including remote locations where traditional infrastructure may be lacking.
