卫星导航系统受扰条件下制导炮弹打击能力分析

Analysis on Strike Capability of Guided Projectile under the Condition of Satellite Navigation System being Jammed

卫星导航/惯性导航的组合导航是制导炮弹的主要制导方式,也是制导炮弹精确打击的关键所在。卫星导航系统主要作用包括定位导航、时间同步和精确制导3个方面。首先介绍卫星导航对制导炮弹的作用机理及影响因素,然后分析卫星导航系统受到干扰后对制导精度的影响,进而对制导炮弹命中精度进行分析。

The integrated navigation of satellite navigation and inertial navigation is the main guidance method of guided projectile,is also the key of guided projectile to precisely attack.The main roles of satellite navigation system include three aspects:positioning and navigation,time synchronization and precision guidance.Firstly,the action mechanism and influencing factors of satellite navigation on guided projectile are introduced,then the impact of jammed satellite navigation system on guidance accuracy is analyzed,and then the hit accuracy of guided projectile is analyzed.
