The accelerometer-based north finder system usually applied dynamic measurement scheme owing to its angular-velocity measurement principle. 加速度计寻北仪由于其角速度测量原理采用的是动态测试方案。
The mathematical model between position error and north seeking error is gotten through error theory and partial derivative principle. 运用误差理论和偏导数原理，推导出转位误差与寻北误差二者之间的关系模型。
