<p>The invention relates to a method for the continuous calibration of a sensor for the three-axis measurement of a vectorial physical field (G, H) by determining the axial biases of measurements by means of calculating a current value (vp) of the parameter(s) (p) of a predetermined model (MP) approximating a current set (EC) of stored data depending on the measurements provided by said sensor, the value of the parameter(s) (p) representing said axial biases, wherein the method comprises the following iterative steps: selecting an additional set (EA) of at least one new datum, depending on the measurements provided by said sensor; determining a following value (vp') of the parameter(s) (p) from the projection of said current value (vp) onto a geometric locus depending on a subset (SE) of the combination of the current (EC) and additional (EA) sets; updating the current value (vp) of the parameter(s) (p) to the following value (vp') of the parameter(s) (p); and updating the current set (EC) using the current set /EC) and the additional set (EA).</p> |
