A space station was a form of spacecraft that was constructed with the intention of remaining in a fixed position in space. On occasion they were placed in orbit around a planet or other celestial body for a variety of purposes.
Space stations sometimes were called other things, such as Nerva Beacon. However the design and function of the beacon was still that of a space station. (TV: Revenge of the Cybermen)
