固体运载火箭捷联惯导快速水平对准研究

Research on Rapid Horizontal Alignment of Strap- down Inertial Navigation System on Solid Launch Vehicle

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。

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 vehi- cle, 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.
