Hyperspace tracker

Hyperspace tracking was the ability to detect starships traveling through hyperspace, a feat not thought possible until the First Order utilized it against the Resistance in 34 ABY. The science behind hyperspace tracking was studied by the Tarkin Initiative during the reign of the Galactic Empire, and files about these studies were discovered by Jyn Erso during the Battle of Scarif in 0 BBY. The science was not perfected for several more decades, when a team assembled by General Armitage Hux discovered how to implement the technology.
