Abstract
This paper presents a new algorithm for the onboard calibration of three-axis magnetometers under noisy environment. The ordinary least squares (OLS) estimator is inconsistent for ellipsoid fitting problem. Proper corrections of the OLS estimator are derived, which can provide a consistent solution to the magnetometer's calibration parameters without noise preknown. Simulation and experimental results are presented and discussed, supporting the application of the algorithm in the noisy platform.Keywords
