摘要
本文提出一种分级式分敞信息滤波算法,并通过具体实例研究了它在组合导航系统中的应用。这种算法的特点是主滤波器的计算量小,量测修正只涉及到加(减)法运算。尤其适合于数据采样频率较高、反馈校正间隔较长的组合导航系统。
An algorithm of decentralized information filtering with hierarchical network structures is discussed for the design of integrated navigation system. This algorithm has the advantage of less computation load in the global filter and is especially suitable for integrated navigation system, which has a high sampling rate and low feedback calibration.
