舰艇采用实测舰位法对岸上不可见目标进行远程攻击时，在已获取目标地理信息的情况下，我舰定位误差往往成为影响打击精度的关键因素。针对惯性导航长时间工作产生积累误差，以及卫星导航在战时易受干扰等情况，提出利用对单发弹丸的跟踪与预测，结合提取的岸上目标绝对定位数据和弹丸落点的偏差信息，反向推算发射舰相对岸上目标的位置，可较为精确地修正我舰的绝对定位数据，为后续射击提供修正手段。该方法减少了战时舰炮武器系统对导航的依赖，仅靠对单发弹丸跟踪和预测，即可提高后续对岸射击的精度。

After attaining the geographical information of shore invisible target,the ship’s location error becomes the key factor of long-range attacking by ship’s real-time measuring. INS’s long time working would decrease the data precision,and satellite navigation can be easily disturbed by emery during the war,so this article proposes a new method of computing ship’s absolute location data. By tracking and predicting the ballistic trajectory,this technique calculates reversely the location data of launch ship relative to the target based on target’s absolute location data and bullet’s bias data of falling point,the process provides a new correction means for next firing. By analyses,this method could reduce the gun weapon system’s depending on navigation,and improve firing precision only by tracking and predicting of just one bullet.
