多传感器组合导航联邦滤波技术研究

Research of Mult-sensor Combinational Navigation Based on Commonwealth Filter Technique

文中对多传感器组合导航联邦滤波技术进行了研究,并通过实例进行了仿真计算。得出了联邦滤波器比各子滤波器的估计精度高,比集中式滤波技术的计算量小,而且联邦滤波技术与集中式滤波技术的估计精度相差不大的结论。

The paper researches the mult-sensor combinational navigation of commonwealth filter technique and carries out calculating emulationally by an example,then we obtain that the estimating precision of the commonwealth filter is higher than that of the single filter,the calculation amount of the commonwealth filter is less than that of the centralized filter technique,and the estimating precision of the commonwealth filter is equivalent o that of the centralized filter technique.
