本研究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。
This study is applicable to a new inertial self-seeking north / stable combination system on land vehicles such as tanks. The system adds some inertial devices and corresponding control loops to the steady-sight platform on the tank, so that it also has the function of finding north. The program uses the dual position north seeking method, after two alignments, the solution of azimuth, and the azimuth and horizontal axis simultaneous gyro drift solution and compensation, thereby further improving the north seeking accuracy. The system can be in the car condition, the parking is completed automatically find the North, North Seek time is less than 5.5min; The system also has to maintain the orientation during maneuver, real-time carrier tilt angle and pitch angle and other functions.
