Complete Introduction of Fluxgate Compass
A fluxgate compass is a device used to determine precise geographical direction on a ship. The Fluxgate compass is a crucial and unique tool in maritime navigation because it does not operate automatically like a traditional magnetic compass. Technically, the Fluxgate compass is electromagnetic, functioning similarly to a traditional compass.
The Fluxgate compass is primarily used for ship navigation. Because it is electronic, its error is extremely low. In addition to manual navigation, the compass can also be used when the ship is in autopilot mode. Even map and radar systems use the compass to obtain accurate geographical indications.
Fluxgate Compass
The difference between a magnetic compass and an electronic compass is that the former has a constantly moving pointer to indicate direction, while the electronic compass does not have a pointer. The current flowing through the coils inside the compass indicates geographical direction via digital signals.
Structure and Advantages
It consists of two vertical coils, with a layer of magnetizable material wrapped inside the coils. When current passes through the coils, this material acts like an electromagnet, detecting the horizontal direction of the Earth’s magnetic field. This eliminates the problem of magnetic north interference.
One advantage of installing this type of compass on a ship is that its operation is unaffected by location. It can be installed anywhere, and the directions it indicates are completely reliable. This compass is handy at sea because it is unaffected by position or abnormal motion.
However, a disadvantage of electronic compasses is that they will not function if there is a complete power outage on board, and the crew will have to rely solely on magnetic compasses.
Another essential aspect to consider regarding electronic compasses is the need for continuous inspection of their components. Any problem, even a minor one, can lead to inaccurate compass readings, causing numerous problems for the captain.
Despite some drawbacks, the lock compass is undoubtedly one of the best navigation technologies in the maritime field.
