| 摘 要： | 为了提高复杂环境条件下导弹的导航精度,以GPS/SINS紧组合导航系统为研究对象,首先研究了GPS/SINS紧组合导航系统的数学模型;然后对扩展卡尔曼滤波和无迹卡尔曼滤波的算法进行了详细的分析;最后将这两种滤波算法应用到GPS/SINS紧组合导航系统中。系统仿真结果表明,UKF在位置、速度的估计精度上均优于EKF,并且UKF具有更好的稳定性和收敛性。

| Abstract: | In order to improve the navigation precision of missile under the complex environment.With GPS/SINS Tightly-coupled integrated navigation system as the object of the research,first of all,the mathematical model of GPS /SINS Tightly-coupled integrated navigation system is derived;and then the algorithm of the EKF and UKF are analysed amply.Finally,EKF and UKF are replied to GPS /SINS tightly-coupled integrated navigation system,and the simulation result indicates UKF takes precedence of EKF in the estimation of position and velocity.Moreover,UKF has the better stability and stypticity. |
