Abstract: 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.
Keywords: heading and attitude; quaternion; Kalman filter
