摘要
针对船用航向自动测量设备的特点,从理论上分析了巨磁阻传感器的特征,并建立了航向自动测量系统数学模型。采用磁电阻百倍于普通磁阻的传感器作为航向自动测量系统的地磁测量单元,与加速度传感器、陀螺传感器、温度传感器、微处理器等,构成了系统的基本组成,并对航向自动测量流程、磁场测量单元温度补偿等方面进行了研究。
The characteristics of the giant magnetic resistance （GMR） sensor is analyzed from the angle of ship heading meas- urement application and the mathematical model of automatic heading measurement is built. The proposed system uses a GMR sensor as the geomagnetic heading measurement unit, which features hundred times higher sensitivity than ordinary sensors. The system integrates accelerometers, gyroscopes, temperature sensors and microprocessors with the GMR sensor. The processing flow of automatic heading measurement and the temperature compensation of the magnetic field measurements are described.
