Abstract
The present disclosure relates to an apparatus for ascertaining a rotation angle of a magnetic field orientation-influencing test object with an axis of rotation in the z-direction. The apparatus may include at least three first magnetic field sensor elements, which are sensitive to magnetic field components in the z-direction. The apparatus may include at least three second magnetic field sensor elements, which are sensitive to magnetic field components in an xy-plane. The apparatus may include a device for ascertaining the rotation angle on the basis of a first combination signal which is based on multiple combinations of measurement signals from the first magnetic field sensor elements and the second magnetic field sensor elements.
