A satellite radio or subscription radio (SR) is a digital radio that receives signals broadcast by communications satellite, which covers a much wider geographical range than normal radio signals.

SR functions anywhere where there is line of sight between the antenna and the satellite, given there are no major obstructions, such as tunnels or buildings. SR audiences can follow a single channel regardless of location within a given range.

Because the technology requires access to a commercial satellite for signal propagation, SR services are commercial business entities (not private parties), which offer a package of channels as part of their service —requiring a subscription from end users to access its channels.

Currently, the main SR providers are WorldSpace (Intl.), XM Radio & Sirius (U.S.), as part of their each being proprietary and non-compatible signals, requiring proprietary hardware for decoding and playback. Both these and other services have news, weather, sports, and several music channels.
