An Auger, also sometimes known as an Auger Array, is the Imperium of Man's High Gothic name for the standard high-powered suite of active and passive scanners used by starships, vehicles and some ground-based facilities. These scanners can include radar, infrared detection, ultraviolet detection, lidar, chemical assays, sonar, spectroscopy, and other technologies, all intended to detect and analyse sources of energy and other phenomenon on planets or in the void of space. Augers are most useful for detecting incoming enemy spacecraft, unmasking vital installations on hostile worlds, and for carrying out detailed scans of spatial and planetary discoveries.
