Abstract

Three-axis fluxgate sensors are quite widely used in various industries. However, due to the inherent limitations of their manufacturing process, various deviations can occur. In this paper, we study and analyze the sources of errors of three-axis fluxgate sensors, and construct a corresponding error model. The three-axis fluxgate sensor is successfully calibrated by the extended Kalman filter algorithm. Both simulations and experiments demonstrate that the method is effective in correcting the three-axis fluxgate sensor. In the experimental stage, the error was reduced by two orders of magnitude by applying the extended Kalman filter.
