基于不同局部模型的联合滤波算法研究

Federated Filtering Algorithm Based on Different Local Models

从组合导航系统研究的角度出发,提出了一种基于不同局部模型的联合滤波算法,并对INS/GPS/Doppler组合导航系统进行了仿真。结果表明:该算法不要求局部模型一致,增强了系统的通用性,提高了运算速度。

This paper, in view of the research on integrated navigation system, proposes a new federated filtering algorithm based on different local models. The simulation on INS/GPS/Doppler integrated navigation system is given. The results show that the new algorithm doesnt require an identical local model, which improve the versatility and calculation speed of the system.
