A first sensor signal and a second sensor signal are provided by a sensor unit to an evaluation unit. The first sensor signal is dependent on the angular position and is associated with a first detection position, and the second sensor signal is associated with a second detection position lying about the rotational axis perpendicular to the first detection position. An orthogonal error is converted by the evaluation unit into an amplitude difference between respective amplitudes of the first and second sensor signals based on a coordinate transformation of the first and second sensor signals. Each of the first and second sensor signals are adjusted by the evaluation unit based on the amplitude difference. An angular position of a rotational component is determined by the evaluation unit based on output from an a tan 2-function that takes the adjusted first and second sensor signals as input.
