Tannhauser Gate

The Tannhauser Gate is a location referred to in dialogue in Blade Runner. Roy Batty, played by Rutger Hauer, refers to it while recounting his experiences as a soldier. Given the fact that Earth has offworld colonies in Blade Runner, and the typical functions of devices incorporating the word "gate" in science fiction, it is reasonable to assume that the Tannhauser Gate is a stargate-type construct providing faster-than-light travel between star systems, perhaps located near or in orbit of a colony named Tannhauser.
