基于多台光学经纬仪实时交会的弹道初段解算方案探讨

导弹飞行试验中,初段弹道位置参数一般通过两台光学经纬仪交会测量获得。而由于布站条件限制,这种定位方式的效果往往并不理想,尤其是由位置滤波(或者平滑)得到的速度参数带有较大的随机误差,不能为安控和数字引导提供有效的实时信息源。针对此问题,提出了多台光学经纬仪实时交会定位的方案,并对工程应用中面临的难点和具体问题进行了详细分析。

The Discussion of Computing Scheme for Original Trajectory Based on Realtime Multi Optical-theodolites Intersection

During the missile test,the position parameter of original trajectory is usually gained by intersection measure of two optical-theodolites.Because of the limiting of station distribution,the results of this method are usually not effective actually.And the velocity getting by filter method has larger random error.The realtime data cannot be as an effective information source for safety control and data guide as far as this issue is concerned,the multi optical-theodolites intersection implying on the real ti...
