联邦卡尔曼滤波在INS\GPS组合导航中的应用

Application of Federated Kalman Filtering in INS\GPS Integrated Navigation System

介绍了 INS\GPS 组合导航系统的优点;根据联邦卡尔曼滤波原理,设计了 INS\GPS 组合导航系统的滤波算法;对该组合系统的联邦卡尔曼滤波算法进行了仿真;仿真结果表明,在 INS\GPS 组合导航系统中采用联邦卡尔曼滤波,不仅提高了定位精度,而且保证了滤波的快速性。

This paper introduced the virtue of INS(Inertial Navigation System)\GPS(Global Positioning System)inte- grated navigation system.Based on the principle of federated Kalman filtering,the Filtering algorithm of INS\GPS in- tegrated navigation system is presented.This algorithm is simulated in the integrated navigation system.The simulation results show that the federated Kalman filtering increases the accuracy of position and ensures the rapidity of filtering.
