摘要
研究了挠性寻北仪解算算法,首先介绍了寻北仪的组成和算法原理,在此基础上建立了陀螺和加速度计的误差模型。根据二位置寻北方法,分别推导了寻北系统在基座水平和倾斜情况下的寻北算法,试验表明该算法能满足中低寻北精度要求。
The flexible north finder solver algorithm is studied in this paper. Firstly, the principles of composition and algorithm of north finder are introduced, and on the basis of the establishment of the error model of gyroscope and accelerometer. Regarding the two-position north-seeking method, the north-seeking algorithm is derived for the north-seeking system in the case of base level and inclination, and the experiment results show that the algorithm can meet the requirements of low precision level.
