捷联惯导系统初始对准研究现状及展望

Development and prospects of initial alignment method for strap-down inertial navigation system

  • 摘要: 初始对准技术直接关系到捷联惯导系统(SINS)的导航精度和启动时长,因此一直是惯性导航领域的研究重点和难点。为此,对SINS系统初始对准技术的发展现状进行综述。首先,简述无纬度对准、纬度已知的粗对准和精对准的基本原理,分别指出上述对准技术的优缺点及其适用条件。然后,分析和讨论现有初始对准误差抑制技术的研究热点和作用效果。最后,结合现有方法存在的问题与运载体的发展需求,对未来SINS系统初始对准技术的研究方向予以展望。

     

    Abstract: Initial alignment technology is directly related to the navigation accuracy and startup time of the strap-down inertial navigation system (SINS), and has always been regarded as a challenging focal point in the research field of inertial navigation. This paper makes a comprehensive survey of SINS initial alignment technology, briefly introduces the basic principles of initial alignment without latitude, coarse alignment with known latitude and precise alignment, and points out their advantages, disadvantages and applicable conditions. The research and effects of existing initial alignment error suppression techniques are then analyzed and discussed. Finally, according to the problems of existing initial alignment methods and the development requirements of the carrier, the future research direction of SINS initial alignment technology is predicted.
