摘　　要：利用里程仪辅助捷联惯导系统构成自主式组合导航系统,构造、设计捷联惯性/里程仪组合定位、定向系统卡尔曼滤波器和新算法。并给出了仿真结果,仿真结果表明,该组合导航系统可有效减小速度和位置等导航参数的累计误差。Discuses an independently integrated navigation system（SINS） using the odometer to assist the strapdown navigation system. Construct and designed the SINS/GPS/OD combined navigation system, The observational measures of the SINS/GPS/OD are the velocity＇s defferences between SINS and OD, We adopt a extend Kalman filter to estimate and correct the errors. The result of simulation given in this paper indicate tha the SINS/GPS/OD can effectively improve on the navigation parameters.
