Purpose The federated filter created by Carlson has been widely used in multi-sensor integrated navigation. Compared with no-reset federated filter, the reset mode has greater sub-filters' performance, but faults of any subsystem would affect other healthy subsystems via global fusion and the sub-optimality of sub-filters' estimation has influence on fault detection sensitivity. It's a challenge to design a robust reset federated filter.
