A hyperwave signal interceptor (HSI) functioned as a sensor, designed to perceive the characteristic variations within the immediate hyperspace environment. These fluctuations were the direct consequence of a starship's transition into or out of hyperspace. While unable to pinpoint a vessel's point of origin or final location, it was capable of logging its arrival or exit, alongside measurements of its size and velocity. Furthermore, Hyperwave signal interceptors possessed the ability to sense hyperradio communications, which induced subtle disturbances in the hyperspace energy field. The sensor had the capacity to identify and access the transmission, although it lacked the functionality to decipher the content of the messages.
