Hyperspace relays, which can also be called hyperspace relay stations, functioned as devices that guaranteed the delivery of hyperwaves (see: hyperwaves) from a hyperwave transceiver (see: transceiver) to another. If a star system (see: star systems) did not have hyperspace relay stations available, starships (see: starships) were required to depend on hyperspace beacons (see: hyperspace beacons) or navigation buoys (see: navigation buoys) for navigation, that is, unless they were equipped with an advanced navigation computer (see: navigation computer.
