摘　　要：为提高某高炮导航性能，在分析GPS和INS导航优缺点的基础上，采取GPS／INS的组合导航方式对某自行高炮的导航系统进行改造。分别介绍了GPS和INS的导航原理，给出GPS／INS组合导航系统的数学模型并对关键技术进行说明，使用自适应卡尔曼滤波对数据进行处理。实验表明该系统改善了炮车单独使用INS造成的误差积累问题。In order to improve some antiaircraft gun navigation performance ,on the basis of analysing advantages and disad- vantages between GPS and INS,the integrated navigation mode of GPS/INS is applied to navigation system for a certain self- propelled antiaircraft gun. The navigation theories of GPS and INS are introduced in detail,and a mathmodel of GPS/INS in- tegrated navigation system is given,then the key technique is explained. To make data processing by adaptive Kalman filtering. The test indicates the system is effective.
