<p>A magnetic field sensor assembly (401a, 401b) for measuring an angular direction (Õ) of a sensed magnetic field (H appl ) relative to the assembly, the sensor assembly comprising: a sensor (404a, 404b) of a first type configured to sense an orientation of the sensed magnetic field; a sensor (402, 406) of a second type configured to measure an orientation and a direction of the sensed magnetic field; and processing circuitry (403, 405) connected to each of the magnetic field sensors, the processing circuitry being configured to process output signals from the sensor of the first type to determine an uncorrected sensed magnetic field angle and to apply an offset angle to the uncorrected magnetic field angle dependent on a logical combination of signs of output signals from the sensors of the first and second types.</p> |
