DRADIS (from the terms Direction, RAnge, and DIStance, or alternatively Declination, Right Ascension, and Distance), is a tracking technology used in the re-imagined Battlestar Galactica miniseries and television show, as well as related spinoff media.
Use in series
The system is used for detecting and scanning vessels and other objects in a 3-dimensional space. Although the terms "range" and "distance" are synonymous in meaning, they indicate different factors of 3-dimensional tracking. One term is used to describe a target's horizontal position along the planar X and Y coordinates relative to the centerline of tracking vessel. The other represents the target's vertical position, or elevation, relative to the tracking ship centerline.
Although the DRADIS appears multi-functional with the ability to scan for water and radiation signatures, the technology is generally used within the show as the primary means of detecting other vessels and spatial bodies, for example a Cylon Basestar or the planet Kobol.
The season two episode "Flight of the Phoenix" reveals that carbon composites are not detected by DRADIS systems.
