Abstract
With the characteristics of good observing, simple structure and high reliability and so on, The CNS/SINS Integrated Navigation Using Star Tracker applies to seafaring and large-scale airborne platform in aerosphere. However, the star tracker can track only one star every time and celestial positioning depends on the performance of horizon measurement. Moreover, the horizon measurement of strapdown inertial navigation system is digital and low accurate. This brings on a reduced performance of CNS/SINS integrated navigation. Therefore, a new CNS/SINS method is advanced. With several observations of single star tracker, the attitude determination is realized. Finally, the CNS/SINS integrated navigation system is established. Both the simulation and experimental results demonstrate that the performance of this integrated navigation system is excellent. In this way, the output divergence is restrained and the accurate of positioning and heading is improved. In a word, the CNS/SINS method applies to the long-distance and long-endurance airborne platform.
