摘　　要：陀螺的漂移和随机误差是影响动调陀螺寻北的主要因素。提出了三位置寻北方案,消除了陀螺漂移对寻北的影响。准备时间、采样时间、低力矩维持电压和堵转时间等参数设置会直接影响寻北时间和寻北精度。通过实验数据设置合理的参数可减小陀螺随机误差。实测结果表示寻北精度从0.2°提高到0.05°。The gyro drift and random error are the primary factors which influence the performance of the dy- namically tuned gyroscope north finding system. The tri-position north finding scheme is proposed to eliminate the effect of gyro drift on the north finding. Prepare-time,sample-time,low-moment holding voltage and block-rotation time can affect the time and the precision of north finding. These Parameters can be set to decrease gyro random er- ror by testing data. The test results show that the precision of north finding is raised from 0.2° to 0.05°.
