摘　　要：研究了GPS/DR/DM组合导航系统在车辆兵器上的应用,通过分析GPS(GlobalPositioningSystem)和DR(Dead-Reckoning)各自导航、定位的原理及特点,以及DM(DigitalMap)的特点,设计了一种新型的低成本车辆兵器GPS/DR/DM组合导航系统,并且用自适应的扩展卡尔曼滤波器对组合系统进行了仿真实验,证明了本系统的可行性。结果是车辆兵器GPS/DR/DM组合导航系统无论从精度还是可靠性来说较常规的导航系统都有明显的改善和提高,充分说明GPS/DR/DM组合导航系统是一种很有应用前景的车辆兵器导航系统。This paper aims to study the application of GPS/DR/DM integrated navigation system in vehicle for weapon.Based on the analysis of the respective principles and characters of GPS and DR in navigation and positioning,a new kind of lower cost vehicle for weapon GPS/DR/DM integrated navigation system is designed,and is simulated with the integrated system by using the adaptive and extended Kalman filter,and the simulation test proves its feasibility.Results vehicle for weapon GPS/DR/DM integrated navigation system,therefore,is improved and advanced in' both reliability and precision.In the end,this paper concludes that GPS/DR/DM integrated navigation system is a prospective vehicle for weapon navigation system.
