Fixed Satellite Service (FSS) refers to a type of satellite communication that provides dedicated links between fixed ground stations. These services are primarily used for broadcasting television, internet access, and data transmission. FSS satellites are positioned in geostationary orbit, allowing them to maintain a constant position relative to the Earth. FSS operates by transmitting signals from a ground station to a satellite, which then relays the signals to another ground station. This technology enables reliable communication over long distances, making it essential for various applications, including telecommunications, broadcasting, and remote sensing.
