Astroinertial Navigation for Cruise Applications

Abstract

Astroinertial navigation systems provide the greatest accuracy and a bounded position error over an extended use-time and distance. These systems are autonomous, passive, non-jammable and automatic. The key element of the system, the astroinertial instrument, is a three gimbal stable inertial platform with an integral two degree of freedom day-night star tracker that operates automatically world wide. The system provides navigation, guidance, and control with the best accuracy available in any self-contained navigation system, from subsonic through hypersonic speeds. The present operational system described in this paper, NAS-26, provides bounded cruise navigational performance--better than 1,000 ft. CEP--throughout flights of short or long duration (specific performance classified).
