Where Are The Magnetic Compass And Gyrocompass Used?

Mar 04, 2018|

The magnetic compass is available in any case and is therefore called the standard compass.

More accurate than gyro compass, so power compass directed at ordinary times, but the premise of gyro is electricity, and the control system of gyro is very complex, these are not problems, once a problem, gyro is unavailable. And then you have to use the magnetic compass.

The magnetic compass is an autonomous system that relies less on the outside world. But ship magnetism and geomagnetism will make the magnetic compass produce a certain error, two or three degrees, or three or five degrees, but generally not to let it lose its directivity. This is the difference from the electric compass, which can't be pointed at once it has lost power or malfunction.

In the lifeboat is to use the magnetic compass, without the conditions of the gyrocompass. So each lifeboat is equipped with a small magnetic compass. The magnetic compass is required to be proofread in the maintenance of lifeboat.

The ship is generally used for 365 days, but every flight class needs to check the magnetic compass and check with the gyrocompass to determine the compass error and log in the logbook. Why? On the one hand, it is normal to ensure that the magnetic compass is normal. If it is not checked, if the true gyrocompass is broken, the magnetic compass will be used to find out that the magnetic compass is also bad. Each class is checked to record the deviation of the compass, because there is latitude and longitude, there is a course, there is a lot of compass, so the magnetic difference and the deviation are easy to calculate. , though we won't go to calculate which day really gyrocompass is out of order, all these are recorded in the compass error on the log book is very precious, can help us to analyze variation in the compass error and deviation, because of the variation is related to the geographical, compass error is related to the course, so we record the position, course, compass error, and it is useful.
