Nuclear Detonation Sensors, or NUDETS
in militaryspeak, are devices which nations use to detect (duh
) nuclear detonation
s on the earth's surface. The instrument was originally known as a bhangmeter
(oh, those funny men).
One type consists of infrared cameras aboard other-purposed satellites such as MilStar and possibly GPS, these sensors constantly watch the earth for the characteristic bright, bright double flash of an atomic explosion, known as a 'High Energy Event.' They are monitored from U.S. Space Command SPACECOM in Colorado.
