一种新的高精度天文导航方法

A New Method of High Precision Celestial Navigation

摘要:

介绍了一种新的高精度天文导航方法,该方法构建了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。

Abstract:

In this paper, a new method of high precision celestial navigation was introduced, with the method, a calculation model of attitude and course was constructed about celestial navigation in the celestial sphere coordinate system. The model conducted attitude calculation and course calculation on the premise of not using INS attitude data, conducted precise attitude and course of carrier by the evolution of the model being constructed, and it could correct attitude error and course error as a result of inertia gyro drift of inertial navigation equipment.
