| 摘 要： | 为解决组合导航系统子系统故障时导航精度降低这一问题,根据事先制定的重构规则进行系统重构,使得导航系统发生故障时仍能正常工作地思想,制定了INS/GPS/ADS组合导航系统的重构规则,并采用Simulink进行了仿真。结果表明,在发生故障时,基于联邦滤波组合导航系统的重构技术能保证系统在故障时仍能以一定的精度进行导航。

| Abstract: | To solve the problem lower accuracy of navigation system when navigation subsystem failure,a method can be used is the reconfiguration of the system according to the pre-established rules,make sure of that the navigation system can be still proper functioning when subsystem failures.According to this thinking,the reconstruction rules for INS/GPS/ADS integrated navigation system has developed.The results show that,integrated navigation system based on federal filtering reconstruction technology can guarantee that the system still works to a certain degree of accuracy in the event of subsystem failure. |
