A sensor system and a joystick including the sensor system. The sensor system comprises a magnetic field sensor, and first and second magnetic sources. The first magnetic source is rotatable relative to a sensitive surface of the sensor and generates a first magnetic field contribution of at least quadrupolar order. The second magnetic source is pivotable with respect to the sensitive surface and generates a second magnetic field contribution. The sensor is configured for detecting at least an in-plane component of a superimposition field of the first and second magnetic contributions at a plurality of lateral measurement locations on the sensitive surface, obtaining measurements, and determining a rotation angle for the first source from the field gradient measurements and two angular directions for the second source from the field mean measurements. Lateral measurement locations are arranged into two pairs of diametrically opposite measurement locations with respect to the sensitive surface.
