| 摘 要： | 研究了适用于坦克等陆用战车上的一种全新的惯性自寻北/稳瞄组合系统.该系统对战车上的稳瞄平台增加一些惯性器件以及相应控制回路,使其同时具有了寻北功能.本方案采用双位置寻北计算法,经过两次对准,解算出方位角,且对方位及水平两轴同时进行陀螺漂移的解算及补偿,从而进一步提高了寻北精度.本系统可以在车载条件下,停车完成自动寻北,寻北时间小于5.5min;本系统还具有在机动时进行方位保持、实时提供载体倾斜角和俯仰角等功能.

| Abstract: | A brand-new method of automatic north-seeking/sight-stabilizing is introduced for usage in land fighting vehicles such as tank, etc. Some inertial devices are installed additionally on the platform along with relative control circuits to make its function of North-seeking possible. Double-position-calculation is adopted in this method, and by alignment at two sites the azimuth angle can be figured out. Also the orientation and the horizontal shifts of the gyro are simultaneously measured and compensated so as to improve the accuracy of north-seeking.The system can automatically seek north when the vehicle is immobile. And the time consumption is no more than 5.5 min. Besides, the system can keep azimuth-angle and provide tilt angle and pitch angle of the vehicle. |
