In a method for determining an offset of measured values of a multiaxial directional sensor using a superposed signal, a large number of multiaxial measured values are recorded first. Measured values, which are recorded in different orientations of the directional sensor, form a geometric figure in a coordinate system resulting from the measuring axes of the sensor, the ideal form of the geometric figure being known and the ideal center point of which being located at the origin of the measuring axes. In the case of a biaxial sensor, the geometric figure is a circle; in the case of a triaxial sensor, it is a sphere around the origin. The superposition caused by the interference is reflected in that the center point of the geometric figure is shifted in relation to the origin of the measuring axes. The offset is measured by determining this shift. |
