Abstract :
In this paper, one attitude measurement and data storage system is introduced based on ARM microprocessor, three-axis micro acceleration sensor and three-axis micro magneto-resistive sensor. The system can be used to measure pitch angle, yaw angle and roll angle. The algorithm of attitude is deduced, the hardware and software are designed. It can be used to measure attitude of vehicle, aircrafts and robot etc. Vehicle´s attitude measurement method is illustrated in detail. And the acquired data can be recorded and processed in real-time by the system. The theory calculation results indicated that the original data error of the sensors can be compensated by Kalman filtering.
