摘要：

A regularization three-axis magnetometer calibration algorithm is proposed for vehicular navigation. Due to the constrained manoeuvre of the vehicle, a linear observational equation system for calibration of three-axis magnetometer is severely ill-posed. The traditional calibration methods may result in unreliable solutions in the lack of dealing with ill-posed problem. The ill-posed problem is solved by using the truncated total least squares (TTLS) technique. This method can effectively suppress the errors on both sides of the observation equation. Furthermore, the TTLS method is used to solve the ill-posed problems. A vehicular navigation experiment is conducted to validate the effectiveness of the method. The results show that the proposed algorithm can effectively mitigate the ill-posed problem and obtain more stable numerical solutions. The mean value of the heading angles from the calibrated measurements is equal to 1.5°, which meets the vehicular navigation application. ©, 2015, China Ordnance Society. All right reserved.
