| 摘 要： | 针对SINS／GPS的速度、位置组合方式中，GPS接收机的位置测量误差相关的问题，提出了一种序贯形式的Kalman滤波算法。这种算法既具有计算量小的优点，又能克服由于GPS位置测量误差相关性带来的滤波性能变差的问题，实现对SINS／GPS组合系统信息的有效融合。通过仿真证明了该算法的有效性。 |

| Abstract: | Based on the SINS/GPS integrated navigation, a sequential estimation method for integrated information processing is presented. The algorithm has smaller computation amount and better performance than that of Kalman filter in information processing. It can overcome the deficiency of Kalman filter whose performance in information processing will be corrupted when the position measurement noises of GPS receiver are not white noises. This algorithm can realize more effective information fusion for SINS/GPS system. Simulation shows that this algorithm is valid. |
