| 摘 要： | 针对行进中对准初始航向角为大失准角的问题，提出了把航向信息耦合到Kalman滤波器量测方程中的方法使航向角收敛。通过激光惯导跑车试验数据分析，在大失准角情况下，航向角都能快速的收敛，对捷联惯性导航系统在行进中初始对准领域的推广应用具有实际意义。

| Abstract: | On the dynamic base alignment, the initial heading maybe is large misalignment angle. In order to make the error converge to zero, a method that Kalman filter with heading coupling is proposed. The simulation results show that this method can quickly eliminate the divergent trend of heading. The method can be used on the dynamic base alignment. It will have more and more bright future. |
