Claim 9:
10. A feedback system for sensing a steering position of a nose wheel assembly for an aircraft, the nose wheel assembly having a first element rotatably associated with a second element about an axis, wherein a rotational position of the first element relative to the second element corresponds to the steering position of the nose wheel assembly, the feedback system comprising:
a first magnetic field sensor fixedly positioned relative to the first element and configured to sense a first element orientation;
a second magnetic field sensor fixedly positioned relative to the second element and configured to sense a second element orientation; and
a controller programmed to determine the steering position of the nose wheel according to the sensed first element orientation and the sensed second element orientation,
wherein the first magnetic field sensor is configured to sense an angle θf between a first magnetic field sensor frame of reference and a first sensed magnetic field direction, the the magnetic field of the earth, and the second magnetic field sensor is configured to sense an angle θr between a second magnetic field sensor frame of reference and a second sensed magnetic field direction.
