捷联惯导系统已成为提升舰载武器性能的必要手段,而初始对准一直是捷联惯导系统的一项关键技术。本文总结了舰载武器用捷联惯导的初始对准方法,重点从误差模型、观测模型和最优估计算法三个方面详细介绍了传递对准的研究现状;并从解析自对准和惯性析自对准两个方面介绍了自对准方法的研究现状。最后,对舰载武器用捷联惯导的初始对准未来的发展趋势进行了展望。
Strapdown Inertial Navigation (SINS) has become a necessary means to enhance the performance of ship-borne weapons, and initial alignment has been a key technology in SINS. This paper summarizes the initial alignment method of SINS for shipborne weapons, and focuses on the current research status of transmission alignment from three aspects: error model, observation model and optimal estimation algorithm. From the analysis of self-alignment and inertia This paper introduces the research status of self-alignment method from two aspects of self-alignment. Finally, the future development trend of initial alignment of SINS with shipborne weapons is prospected.
