| Abstract: | To improve the reliability and accuracy of INS/GNSS integrated navigation system,an information fusion scheme of SINS/GPS/Galileo/RDSS integrated navigation system was designed,and the chi-square testing method based on probability distribution was adopted to improve the fault tolerance and the reliability of the system.On this condition,a new self-adaption distribution algorithm based on the fault state detection was adopted,and the model of navigation system was established.The states function and measure... |
