摘　　要：本文研究了某型号飞机上ＧＰＳ／平台惯性组合导航系统中降阶卡尔曼滤波的设计方法。文中提出了一种降阶滤波器结构，并讨论了模型误差的伪随机噪声补偿方法。采用蒙特——卡洛分析法对降阶滤波器的实际误差进行了数字仿真，结果表明：本文提出的这种降阶滤波器能保证组合系统的导航精度。An effective reduced order kalman filter for the integrated GPS and platform inertial navigation system,which is used for a aircraft,is presented in this paper,the equations of the reduced order filter are given,and the pseudo random niose model error compensation method is studied On the other hand,by error analysis of the reduced order filter and computer simulation,we see that the presented reduced order filter can ensure accuracy of integrated navigation system The scheme of integrated navigation system with the reduced order filter has great value of application
