基于分层融合结构的组合导航系统仿真分析

Simulation Analysis on Hierarchical Fusion Architecture for Integrated Navigation System

依据多传感器信息融合理论,将分层融合结构是应用到组合导航系统中,并与目前广泛应用的联合滤波算法(Federated Filtering)进行了比较。对INS/GPS/Doppler系统的仿真结果表明,有序分层融合结构可有效地应用于多传感器组合导航系统,并且导航精度优于联合滤波的结果。

The hierarchical fusion architecture is an important mode for multisensor information fusion. This paper tries to apply the architecture to the integrated navigation system, and compares it with the Federated Filtering algorithm. The simulation results on the INS/GPS/Doppler integrated navigation system show that consecutive hierarchical fusion architecture is effective for integrated navigation system and can get better results than that of the Federated Filtering algorithm.
