horizon detector

An infrared device used in satellites and rockets to determine a heat horizon for the Earth at altitudes (above 200 miles) where the visible horizon cannot be discerned. The device scans the infrared emittance of the Earth, determining the horizon as the point where the presence of these emittances is sharply reduced.
