| Abstract: | Based on the reentry navigation requirements of a reusable boost vehicle,in order to ensure reentry navigation with high precision and high reliability in the highly dynamic environment,a kind of improved strong tracking unscented Kalman Filter was used for state estimation and tracking.Considering to the shortcomings of the traditional fault detection method resulting from the residual errors of the Kalman filter,a kind of novel fault detection method was developed for checking the working state of each na... |
