| Abstract: | Aimed to the problems in high dynamic positioning of spacecraft, the integrated positoning project based on the information fusion of Inertial Navigation System（INS） and Global Navigation Satellite System（GNSS） was brought forward. Based on the information fusion model of INS/GNSS integrated positioning and the analysis on abnormity in high dynamic positioning, the estimation and processing methods were designed. Malfunction simulation and management indicated that the influence on position precision could be decreased to a certain extent after correction and the method in this paper could improve the reliability in high dynamic positioning. |
