NIGHT VISION NAVIGATION

Abstract:	PRELIMINARY TESTING has indicated that night vision (passive ambient light amplification) telescopes can be adapted to optical navigation instruments. When mounted on a sextant, the night vision scope enables the navigator to view the horizon throughout the night, thus extending the time when star sights can be used. As a terrestrial instrument, mounted on a bearing circle, the NV scope permits viewing of lighted or unlighted navaids or geographic points at night far beyond the normal optical range. The units which have been tested for navigation purposes provide a system light gain of about 2100 over naked eye viewing.
