A comparison of the readings of the gyrocompass and magnetic compass shall be carried out every hour so as to maintain the fixed course of the ship and to determine and check the deviation and variation of the magnetic compass.

Fluxgate sensor inducts the environment magnetic field, outputs the compass course signal to the CPU system. This signal then is transformed into digital signal. CPU processes it and then gains compass course. When use rotary mathod to measure the deviations, CPU first collects timed the compass course come from the Fluxgate sensor, then calculates automatically their deviations and the correspondent coefficients. Based on all this, CPU can calculates out the real-time magnetic course or the real-time ture course, then sents them to display on the digital displayer.

本系统采用磁通门传感器来直接敏感合成磁场，输出罗航向直流感应电压信号送A/D转换器进行转换，并经CPU计算处理得到罗航向度数值，以及利用&旋回法&测定自差时，CPU按照船舶旋回的角速度定时地采集罗航向度数值，在此基础上CPU自动地计算出各采集罗航向上的白差，再由此计算出自差系数，并实时地解算出磁航向值或真航向值，送数码显示器显示。
