摘要
首先介绍了车辆组合导航系统的工作原理及系统间的相互校正和切换问题,然后研究了联合卡尔曼滤波技术的应用,最后提出了一种自适应信息融合方法,实现了GPS定位系统和航位推算系统间的最优综合校正。
The operational principle of integrated navigation system for vehicle is given, then calibration each other and switch of the system are discussed and the application of federated Kalman filtering technology to multisensor system is studied. In the end, we advance an adaptive information fusion to achieve best integrated calibration between GPS and dead reckoning.
