摘要
系统地分析了惯导/双星组合的多种不同模式及其相应的数学模型,不同组合模式的性能特点;建立了最优滤波器和降阶滤波器,比较了不同滤波器对组合精度的影响。仿真表明,利用惯导与双星系统组合,可以有效地克服惯导和双星单独工作的缺点,提高导航系统的精度、可靠性。
Several different integrating patterns of INS/DOUBLE SATS and their corresponding math model are established. The performance of different pattern is analyzed synthetically.The optimal and sub-optimal Kalman Filters are set up and the filtering algorithm is put forward.The effect on the precision caused by selecting different kind of Filter is compared.The simu- lation results show that the shortcomings of the INS and the DOUBLE SATS can be restrained effectively by integrating.The precision of the navigation system can be improved as well as its reliability can be enhanced.
