提出了一种适用于新概念太空武器—天基导弹的初始对准方案。基于天基导弹距目标距离远、速度快、需要从空间机动平台快速发射的特点,研究了一种适于天基导弹的动基座快速精确对准方案。利用空间机动平台提供的姿态角信息首先快速完成粗对准,然后在天基导弹发射后,利用弹载星敏感器引入的精确位置和姿态角观测信息,提出了一种新的位置+姿态角匹配的对准方法,以实现对天基导弹的精对准。详细推导并建立了天基导弹动基座对准系统量测方程。最后,通过仿真验证了该方案的可行性,在10 s时间内,对准精度可达到一个角分以内。
Proposed an initial alignment scheme suitable for the new concept of space weapon-space-based missiles. Based on the fact that the space-based missile is far away from the target and fast, and needs to be rapidly launched from the space mobile platform, a rapid and accurate alignment scheme for a space-based missile is proposed. Based on the attitude angle information provided by the space mobile platform, the coarse alignment is completed quickly. Then, after the space-based missile is launched, a new position + attitude angle is proposed by using the accurate position and attitude observation information introduced by the missile’s star sensor Matching alignment methods to achieve fine alignment of space-based missiles. Detailed derivation and establishment of space-based missile dynamic pedestal alignment system measurement equation. Finally, the feasibility of this scheme is verified through simulation. Within 10 seconds, the alignment accuracy can reach within one corner.
