摘　　要：为提高磁悬浮寻北仪的定向精度，介绍了磁悬浮寻北仪粗一精寻北过程，分析陀螺漂移对定向结果的影响，推导出常值漂移下粗寻北的误差公式，计算得到常值漂移对粗寻北定向精度的影响，并证明常值漂移不影响精寻北的寻北结果，研究定向系数误差对寻北仪的初始架设角度的影响，给出寻北仪的初如架设角度范围。In order to improve orientation accuracy of magnetic suspension gyroscope. The progress of coarse north-seeking and precision north-seeking is discussed. The influence of gyroscope drift is analysed on orientation result. Error formula of coarse north-seeking is infered below constant drifts existence. The influence of constant drifts in coarse nolth-seeking is calculated. Constant drifts is proved that it has not effect on precision north-seeking. The influence of orientation coefficient toward initial setting place angel is studied. The angle range of initial setting place is given.
