摘要
文章论述航向姿态参考系统的应用领域及市场需求情况,分析基于MEMS的航向姿态参考系统的结构组成,推导航向姿态的四元数表示法。基于卡尔曼滤波算法进行信息融合,给出卡尔曼算法的流程图,搭建航向姿态参考系统的硬件电路。
This paper discusses the application field and market demand of heading and attitude reference system, analyzes the structural composition of heading and attitude reference system based on MEMS, and deduces the quaternion representation of heading and attitude. Information fusion is carried out based on Kalman filter algorithm, the flow chart of Kalman filter algorithm is given, and the hardware circuit of heading and attitude reference system is built.
