Using three-axis accelerometer and three-axis magnetometer, an attitude measurement system based on MEMS for micro air vehicle is designed. The system uses C8051F MCU to collect datas of sensors,and datas are sent to upper PC by serial communication, then four element algorithm is used for data fusion and attitude calculation, the pitch, roll, heading angle is displayed on the interface of upper PC%利用三轴加速度计和三轴磁强计,设计了基于MEMS技术的微型飞行器姿态测量系统.系统采用C8051F单片机进行各传感器的数据采集,通过串口通信将采集的信息发送到上位机,用四元数解算算法进行数据融合和姿态解算,将俯仰角,横滚角、航向角等信息在上位机界面上显示出来.
