Imperial Sleeper

An Imperial Sleeper was a type of tracking program used during the war between the Rebel Alliance and the Galactic Empire. The program could be installed into a starship's systems and was tied to the ship's clock. Triggered by the turning of the clock at set times, the program would become active and report the ship's current course and position to the nearest Imperial world in a coded burst.

Shortly after the Battle of Yavin, Alliance agents Luke Skywalker and Nakari Kelen were on a mission to rescue the slicer Drusil Bephorin. While preparing to leave the planet Kupoh, Bephorin found an Imperial Sleeper that had been installed into Kelen's ship and removed it before they continued their escape from Imperial pursuit.

Behind the scenes
Imperial Sleepers were first mentioned in the canon novel Heir to the Jedi, written by Kevin Hearne and published on March 3, 2015.
