Fuel computer

A fuel computer was a part of some starships' operational systems. It kept track of where and when the ship was refueled.

By cross-referencing planets a subject was known to have visited with the planets they refueled on, one would be able to calculate where else the subject may have gone. Jedi would use this technique to track down smugglers.

In 22 BBY, Anakin Skywalker and Ahsoka Tano tracked the bounty hunter Cad Bane using his fuel computer, as he had wiped all other memory from the databank of his ship, the Xanadu Blood.
