Sensor beacon

A sensor beacon, or a sensor marker, was a type of sensor that was designed to transmit its exact position. Sensor beacons were attached to people, vehicles or objects, often discreetly, in order to track them. Some sensor beacons could also scan the individuals in their vicinity.Bloodline On the planet Barton IV, a perimeter of sensors were used to keep wildlife away from the Imperial Depot. They were also used to mark the perimeters of planetary facilities. When establishing Chopper Base on the planet Atollon, members of the Phoenix Cell, such as Lieutenant Dicer, placed sensor markers around the base in order to detect incoming vehicles. After their encounter with the spidery krykna, the rebels discovered the sensors repelled the creatures, and used the sensors to keep them away from the base.
==Behind the scenes==
In "The Holocrons of Fate," Ezra Bridger refers to the sensor beacon as a "thumper," a reference to the device used to summon sandworms in Frank Herbert's Dune novels. It has been posited that Herbert's classic 1965 science fiction novel Dune had a heavy influence upon Star Wars.
