摘　　要：为了把船上常用的机械平衡式磁罗经指示的船首角用数字化的方式在雷达或电子海图等设备上集中显示,采用了最新的意法半导体公司推出的具有三轴磁力计和三轴加速计集成合一的传感器模块LSM303DLH,通过读取内部实时状态的的6个变量数据,从而计算出航船的前俯仰角、侧倾角及与地平面磁北方向的航行角,航行信息通过数据线传送给终端集中处理显示,从而可方便船舶的驾驶与控制,提高安全系数。采用LSM303DLH制作的磁罗经传感器转换精度可达1°内,能满足普通航船的使用需要。In order to centralize display the commonly used bow angle of mechanical balance type magnetic compass on equipment with digital type such as radar or electronic chart, using the latest sensor module LSM303DLH of STM which concentrated triaxial magnetometer and triaxial accelerometer, through read- ing six variable data of internal real-time state, calculated the down before elevation and heel angle and the direction of the magnetic north sail angle of the ship, navigation information through the data transfer to the terminal concentrated processing, which can control and drive easily, improve safety coefficient. The magnetic compass sensor which was made of LSM303DLH could reached 1 degrees, so it could reached the needs of general sailing.
