摘　　要：导弹弹载组合导航系统的测试评估实现难度大,现有数字仿真和实弹飞行试验难以兼顾准确度、有效控制开发成本和研制进度要求。设计了一套基于半实物仿真平台的组合导航评估系统,通过仿真计算得到导弹运动轨迹数据,控制GNSS模拟器仿真生成GNSS信号,利用三轴转台和加速度计电流注入技术模拟角运动和线运动环境,在对采集到的真实IMU和GNSS接收机输出数据进行同步的基础上,实现实时组合导航算法并对导航结果进行分析评估。该系统可以获得最接近真实情况的测试效果,大幅降低研制成本,是一种理想的弹载组合导航评估系统。It＇s a challenge to design a measurement and evaluation system for missile-borne integrated navigation system. Existing digital simulation and live ammunition flight test are difficult to balance the test accuracy and development costs and research progress. A kind of hardware-in-the-loop simulation system is designed. The trajectory is generated by a simulation computer. A GNSS signal simulator can transmit corresponding signal under control. Triaxial turntable and current injection technology for accelerometer are used to simulate angular and linear movement. Real-time navigation algorithm and its evaluation are available based on time synchronization of IMU and GNSS data. It＇ s an appropriate evaluation system for integrated navigation which can provide realistic simulation environment, and the development costs will be substantial reduced.
