| Abstract: | A new fault detection method is proposed for the integrated navigation system. Fault detection is undertaken by checking the consistency between the global state estimate and the local state estimate of federated filter by means of the chi-square test (CST). Meanwhile, the fault isolation method is also discussed. The simulation and laboratory experimental results show that the new method is very efficient and practical; the reliability and safety of the system can be improved. |
