Abstract

The present invention relates to a field-sensor device comprising a first field sensor with a first sensor response to a field, the first sensor response measured in a first orientation to produce a first sensor signal, a second field sensor with a second sensor response to the field the second sensor response measured in a second orientation different from the first orientation to produce a second sensor signal, and a controller for controlling the first and second field sensors to produce respective first and second sensor signals. The controller comprises a control circuit that converts any combination of first and second sensor signals to equivalent first and second comparable sensor signals in a common orientation, calculates an error signal derived from differences between the first and second comparable sensor signals, and adjusts any combination of the first and second sensor responses to reduce the error signal.
