一种适合工程实用的捷联航姿算法

An Attitude Algorithm for SINS inEngineering Utility

从工程实用的角度出发 ,针对惯性元件输出中存在干扰这一问题对四元数的三子样旋转矢量算法和四阶龙格—库塔法进行了分析和比较 ,指出四阶龙格—库塔法是一种具有工程实用价值的捷联航姿算法 ,并给出了在理想情况和有干扰的情况下算法的仿真结果。

In view of the output disturbance of the inertial component existed in engineering utility,the fouth order RongeKutta method and three samples rotation vector method are analyzed and compared in this paper,and the results show that the fourth order RongeKutta is an algorithm valuable for engineering utility.The simulations are also given under the condition with disturbance and without disturbance respectively.
