Calibration of Magnetic Compass in Magnetic Field Domain Based on Poisson Equation
Abstract：The magnetic compass is an important navigation equipment in the modern vehicles, but it has not been applied in ship navigation. This paper analyzes the reason and mechanism of magnetic compass system in ship according to every kind of error. This paper also study calibration of digital magnetic compass in the special situation. A calibration method based on the Poisson equation in magnetic field domain is introduced. The experimental result indicates that this method is simple and useful in the automatic error compensation and the compensation precision is high, the cost is low.
