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。
A new high-precision astronomical navigation method is introduced. The method builds the celestial navigation attitude and heading solution model in the celestial sphere coordinate system. The model is calculated on the premise of not using inertial attitude data, and the accurate posture and heading of the carrier are obtained through the model building. The attitude error and the heading error caused by inertial gyro drift can be effectively corrected.
