摘要: 该文对姿态计算四元数方法进行了研究.通过对计算姿态矩阵的U-S分解,清楚地表达了不同算法的标度误差、歪斜误差和漂移误差;同时也对整流误差、算法优化以及陀螺输出速率信号的提取阶次与计算误差间的关系等问题作了探讨

关键词: 姿态算法, 漂移误差, 算法优化, 捷联系统

Abstract: The quaternion attitude algorithms are studied in this paper. The scale error, skew error and drift error for algorithms of different kind are clearly described by using U-S fraction of attitude matrix. Coning error and algorithm optimization are also discussed in this paper.
