Emergency locator beacon

An emergency locator beacon, colloquially referred to as a slipbeacon, is an automated signal device used by humans in event of an emergency in space. Given its nickname, it likely uses Slipstream space to carry the distress signal. They 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.
