摘　　要：为了降低捷联惯导系统标定成本和复杂度,提高系统导航精度,针对战车火炮捷联惯导系统的安装特点,提出了一种外场条件下捷联惯导系统的原位快速自标定技术。分析了系统的可观测性,推导了常规多位置标定方案;将等效陀螺信息引入到单一位置初始对准过程中,加快了对准速度和相关状态的估计速度;设计了一种针对战车特色的多位置快速标定方案,并进行了试验仿真。结果表明,该方法能够有效完成系统标定,精度高,速度快,同时条件要求简单,可操作性强,便于实际应用,具有重要的工程应用价值。For the sake of reducing calibration cost and complexity of combat vehicle SINS as well as im-proving the accuracy of SINS,aimed at the installation features of combat vehicle gun SINS,a kind of no-vel in-situ rapid multi-position calibration technology was proposed.The observability of the system was analyzed and the conventional multi-position calibration scheme was derived.The equivalent gyro informa-tion was introduced in the process of single position initial alignment,this accelerated alignment speed and evaluation speed of relative states.The new rapid calibration method directed at the combat vehicle char-acteristics was designed and experimental simulation was carried out.The results showed that the new method can rapidly and effectively accomplish the system calibration with high accuracy.Meanwhile the condition requirements of this method are very simple,its operability is better and it has the convenient practical application,and thus the method has the important engineering application value.
