摘　　要：本文设计了适合列车应用的SINS/GPS/OD组合导航系统,建立了联邦Kalman滤波模型和各子滤波器的数学模型。本文结合了联邦kalman滤波的优势,应用了容错滤波技术,提高了系统的容错能力和可靠性。最后通过仿真试验验证了该组合导航系统能为列车运行提供精确的导航参数。This article was designed SINS/GPS/OD integrated navigation systems that application of the train, Established the Federated Kalman filter model and the mathematical model of each sub-filter. This article combines the advantages of Federated Kalman filtering, applying the faulttolerant filtering Technologies to improve the fault tolerance and reliability of the system. Finally, the simulation tests show that the integrated navigation system can provide aceurate navigation parameters of running train.
