Since the image matching positioning and BEI-DOU positioning in SINS/SAR/BEI-DOU system existed time delay,we put forward two methods to overcome them.First,a new algorithm for solving the measurement delay was proposed based on curve fitting.Second,a new dynamic information distribution algorithm was proposed based on fault detection function.Based on the above two algorithms,we have simulated the SINS/SAR/BEI-DOU integrated navigation system.Simulation results show that the two algorithms can reduce the position error of SINS/SAR/BEI-DOU system to several meters,and improve the capability of anti-disturb.
