ABSTRACT:
A process for automatically correcting alignment errors between the measuring magnetometers of a magnetic gradient meter, consists in adding to such a gradient meter two additional magnetometers perpendicular to each other and to the axis of the measuring magnetometers. The measurements delivered by these additional magnetometers allow, with two coefficients obtained by previous calibration, the two main errors terms to be calculated and the measured value of the gradient to be corrected accordingly, which allows the alignment error to be corrected electronically and automatically.
