Abstract
The present invention relates to a method for calibrating a magnetometer () in which the magnetometer () is arranged inside the windings () of a generator (), a magnetic field being generated by the generator (), a series of measurements of the magnetic field with the magnetometer () being carried out by varying the position of the magnetometer () and/or the electric currents in the windings () between each measurement, the electric currents applied in the windings () also being measured, a parametric transfer model being generated from a parametric measurement model of the magnetometer including parameters for calibrating the magnetometer and a parametric model of the magnetic field, the parameters for calibrating the magnetometer () being calculated by an optimisation algorithm from the parametric transfer model and measurements of the magnetic field by the magnetometer and measurements of the currents in the windings.
