摘要	A improved Rao-Blackwellised Unscented Kalman Filter(RB-UKF)algorithm fused by MEMS-SINS/GPS(Micro-Electrical-Mechanical System/Ship's Inertial Navigation/Global Positioning System) was established when the system has become strongly nonlinear after GPS outage. Firstly, the attitude misalignment was described based on the Euler platform error angle and the nonlinear error model for the SINS was set up. Then, as the state model was nonlinear while the observation model was linear, the RB-UKF algorithm was designed to ensure the accuracy of the UKF and to reduce its amount of computation. Finally, the algorithm structure was designed and its computing procedures when the GPS was in normal or in the period of outage were given. The algorithm was used in an in-car-experiment, and the results indicate that the SINS and GPS are fused by using the method proposed in this paper, the position error is less than 6 m or 7.5 m after 20 s and 40 s GPS outage respectively, which is 1.5 times better than that of Expand Kalman Filter(EKF) algorithm. Moreover, the error convergence time by RB-UKF is 1.88 to 16.5 times faster than that of the EKF, and the amount of computation of measurement update by RB-UKF algorithm is 41.7% smaller than that of the UKF. It concludes that the proposed method can effectively reduce the navigation errors after GPS outages for MEMS-SINS/GPS systems and has advantages in project implementation. 2016, Science Press.
