摘要:

传统的水平对准由于采用了复杂的滤波环节，需要较长的时间来完成水平对准工作，难以满足固体运载火箭捷联惯导快速水平对准的需求。为了满足固体运载火箭的快速发射需求，研究了一种基于导航方式的快速水平对准方法，仿真结果表明，该方法能够在〖WTBZ〗15s内完成捷联惯导的水平对准工作，并且能够克服运载火箭扰动环境对水平对准精度的影响。

Abstract:

Usually, complicated filter algorithm is adopted by the traditional horizontal alignment, which can not meet the rapid launching requirement of solid launch vehicle In order to meet the rapid launching requirement of solid launch vehicle, a rapid horizontal alignment algorithm based on navigation is presented The simulation results show that, by using this method, the inertial navigation system on the solid launch vehicle can finish horizontal alignment in less than 15 seconds Also, this method is suitable for the shake environment of solid launch vehicle.
