| 摘 要： | 介绍了自行高炮陀螺寻北仪传统的标定方法,在测定车体纵轴之后,用已知方位标与真北的夹角和经纬仪测量出的车体纵轴与方位标的夹角,计算出寻北仪的方位基准线与车体纵轴的偏差角,通过补数的方法,使寻北仪的输出值即为车体纵轴与真北的夹角,由此完成标定。分析了传统的标定方法的不足,提出了改进的标定方法,通过试验验证,结果正确,可以提高惯性导航的定位精度。

| Abstract: | Traditional calibration method of gyro-northfinder in self-propelled AA gun system was introduced.After measuring vertical axis of chassis,by use of the angle between azimuth-sign and true-north and the angle of vertical axis of chassis with azimuth-sign measured by theodolite,the error angle between chassis vertical axis and northfinder benchmark axis was calculated.With the help of data compensated method,northfinder output angle of chassis vertical axis was coincide with the angle between vertical axis o... |
