摘要
利用天文导航进行运载体姿态及航向解算是导航领域一个新的研究课题,具有重大的研究意义及应用价值。本文介绍了一种构建在天球坐标系中的天文导航姿态与航向解算模型。该模型在不利用惯导姿态数据的前提下进行计算,通过构建的模型演变得到运载体的精确姿态及航向,可以有效校正惯导设备因惯性陀螺漂移而导致的姿态误差与航向误差。实际应用表明,该模型对于校正惯性陀螺漂移,提高惯导设备精度具有重大意义。
Attitude calculation and course calculation using celestial navigation is a new field of study in the field of navigation, which has great significance and value of research. This paper introduces a calculation model of attitude and course about celestial navigation which be constructed in the celestial sphere coordinate system. The model conduct attitude calculation and course calculation on the premise of not using INS attitude data, conduct precise attitude and course of carrier by the evolution of the model of be constructed,and it can correct attitude error and course error as a result of inertia gyro drift of inertial navigation equipment. The practical application shows that the model has an important part in correcting inertia gyro drift and improving the accuracy of inertial navigation equipment.
