Magnetic flux-gate sensor is limited by the installation and process, its three-components can not be absolute orthogonal between each other, so as to bring with measurement errors for data. In order to solve this problem, a new relational model of the three-axis orthogonal angle and magnetic field error is established, simulated, analyzed inversely and to set up a correction algorithm at end. The experimental results showed that the measurement error of magnetic field is reduced to ±10 n T after using this method to test and calibrate the non-orthogonal degrees of the three-components magnetic flux-gate sensor, and the measurement error has been significantly reduced.
