Introduction Of A New Semi-automatic Measuring And Correcting Device For Yacht Magnetic Compass Deviation.

Yacht magnetic compass is a pointing instrument by geomagnetic action, it is caused by hull magnetic action and pointing error, which is what we call magnetic compass deviation.
As we know, in order to be able to correct the course of navigation and operation, the yacht magnetic compass must be in normal state, and to be in normal state must be corrected and measured out the size of the remaining deviation. At present, most of the yacht magnetic compass deviation measurement is still in use more than one hundred years ago manual operation mode, not only time-consuming and laborious, and the accuracy is also low, the credibility of the deviation table is poor, so a new yacht magnetic compass deviation semi-automatic measurement device. Here's how the device works:
This device is mainly divided into two parts, namely measurement and calibration. The deviation can be determined by the cycle method and the corresponding formula, and the correction of the deviation is by using magnets or soft iron to generate an artificial magnetic force to counteract the effect of hard and soft iron forces on the yacht magnetic compass. In order to achieve this requirement, Hall devices or fluxgate sensors should be selected as linear magnetic field sensors.
The above is the basic introduction of the yacht magnetic compass deviation semi-automatic measurement and calibration device.
