1. A position sensor device comprising:
a first sensor configured for determining a first magnetic field component and a second magnetic field component at a first sensor location, the first magnetic field component oriented in a first direction, the second magnetic field component oriented in a second direction perpendicular to the first direction; and
a second sensor configured for determining a third magnetic field component and a fourth magnetic field component at a second sensor location spaced from the first sensor location, the third magnetic field component oriented in the first direction, the fourth magnetic field component oriented in the second direction;
a processing unit connected to the first sensor and to the second sensor, and
configured for determining a first sum of the first and the third magnetic field component, and determining a second sum of the second and the fourth magnetic field component, and determining an angle based on a ratio of the first sum and the second sum, and outputting the determined angle.
