Distress beacon

A distress beacon is an automated signal device used in the event of an emergency in space. Various forms of distress beacons exist, including emergency locator beacons, while a particular type of beacon that utilizes slipstream space is colloquially referred to as the slipbeacon. Distress beacons are mounted on most human starships, and are compact enough to fit in a cryo-tube.

An emergency locator beacon was used by Cortana when the rear half of the was left stranded in space after the Battle of Installation 00. When Operation: BLOWBACK went awry, Team Black used a slipbeacon to send a distress signal to FLEETCOM. The fetcher Oliver Birch used one after he and his dog Mabel became stranded in deep space in a cryo-tube.
