磁方向测量的一种实用系统

磁方向测量是利用方向传感器测运动动物体相对地磁北的方向角，本文应用单片机对二维地磁感应元件组成的磁方向传感器感测的信号进行数据处理，得出运动物体的磁方向角，并且应用单片机对磁方向向测量系统的罗差，安装误差及传输误差进行补偿，得到了较好满意的结果。

Applied System of Magnetic Heading Measurement

he principle of the magnetic heading measurement lies in the use of magnetic heading sensors to sense the heading of the moving object with respect to the magnetic north. With the help of a single chip computer, the magnetic heading of the moving object is obtained by processing the signals measured by the magnetic heading sensors which are composed of two-dimensional magnetic sensing components.The research results show that using a single chip computer is effective to compensate the compass deviation,the attachment errors and the transmission errors of the measurement system.
