导航算法对捷联惯导系统精度的影响分析

摘要

The navigation algorithm accuracy directly influence the SINS performance.Analysis of attitude updating ve-locity updating and position updating algorithm performance,when the the inertial element was output as incremental form. Derived by simulation experiments:factors affecting navigation accuracy,followed by attitude updating algorithm speed up-dating algorithm and location updating algorithm,which provides reference for further study of the navigation algorithm.%导航算法精度的高低直接影响着捷联惯导系统的性能。在惯性元件输出为增量形式的条件下对捷联惯导系统姿态更新、速度更新和位置更新算法进行分析。仿真实验得出：在影响导航精度的因素中，姿态更新算法最大，速度更新算法和位置更新算法次之。为导航算法的研究提供一定的借鉴。
