摘　　要：基于联邦滤波的捷联惯导与GPS、Loran-C组合导航系统,是利用GPS、Loran-C等子系统提供的参数信息对组合导航系统进行联邦卡尔曼滤波,校正捷联惯导系统的误差。在对系统进行了理论仿真的基础上,进行了海上试验,给出了静态和动态试验的结果。理论仿真和基于实测数据的试验结果表明,此滤波器具有较高的滤波性能和精度,而且提高了导航系统的可靠性。The integrated navigation system of SINS/GPS/Loran-C based on the Federated Filter is focused on.The method makes use of navigation information from GPS and Loran-C to provide the Federated Kalman filter of the integrated system,and to correct SINS.The simulation and experiments in surface ship are carried on and the results are presented.The theoretical simulation and the experiment results of the actual data indicate that the SINS/GPS/Loran-C is effective,reliable,and has higher accuracy.
