DRADIS, or "Direction, RAnge, and DIStance", is a highly sensitive detection, identification, navigation and tracking system, analogous in function to radar, used aboard Colonial spacecraft.
DRADIS can be used in stationary configurations as well on ships.
Carbon composites are largely invisible to DRADIS scans.
A DRADIS contact is an object or objects detected by DRADIS. Contacts are typically identified by cross-referencing with an IFF system (in the case of ships) or an astronomical database (in the instance of planets or other celestial bodies).radiological alarms.
The DRADIS can be blinded by external sources of electromagnetic radiation such as artificial radiation by EMP generators, nuclear detonations, pulsars, star clusters and binary stars, or other phenomenona such as the nebulae.
