Vessel’s degaussing system plays an important role in improving the performance of the magnetic protection. However, during ship sailing, magnetometer will be influenced by a variety of interfering magnetic fields, which will seriously affect the accuracy of degaussing current control. To solve this problem, this paper proposes a degaussing current controller based on magnetometer. With analyzing and processing the real-time data of the magnetic field, the instrument eliminates the impact of the interfering magnetic fields on the degaussing current control. The result of practical application shows that the instrument can detect the continuously changing magnetic fields and accurately control the degaussing current to achieve a good degaussing performance.
