A calibration procedure for calibrations of triaxial magnetometers is presented. The procedure uses a triaxial Helmholtz coil system and an Overhauser scalar magnetometer and is performed in the an Earth's field range. The triaxial coils are firstly calibrated with the help of the Overhauser magnetometer and subsequently a calibration of a digital triaxial magnetometer calibration is performed. As opposed to other approaches, neither Earth’s field nulling system is needed, nor are movements of the magnetometer are needed. A real calibration test was carried out and the extended uncertainty was better than 430 ppm in sensitivity and 0.06 degrees in orthogonality.
