| 摘 要： | 针对在捷联惯导系统中陀螺的误差存在随着时间积累而逐渐增大的缺点,提出了捷联惯导系统+星敏感器的组合导航方案,并进行了仿真及结果分析。以Kalman滤波为基础,通过将捷联惯导系统和CCD光学传感器所测得的飞行器相关姿态信息进行数据融合,估计出组合导航系统的误差状态量,进而修正捷联惯导系统的位置、速度和姿态角。详细推导了捷联惯导+星敏感器组合导航的算法,并通过对仿真结果的分析证实了该方案的可行性和算法的有效性。

| Abstract: | To correct the gyros drift errors that increase with time in the strapdown inertial navigation system,a scheme of integrated strapdown inertial navigation system/star sensor is proposed and the simulation results are given.The strapdown inertial navigation system and charge coupled device(CCD) can provide corresponding attitude data.Fusing these data can estimate the error state value of integrated navigation system and correct the position of aircraft,velocity and attitude angle based on Kalman filtering.The algorithm of integrated strapdown inertial navigation system/star sensor integrated navigation system is educed.Simulation results show that the proposed system is feasible and the algorithm is effective.Subject terms Strapdown inertial navigation system Stars sensor Integrated navigation Kalman(filtering) |
