1. An apparatus for positioning a vehicle, the apparatus comprising:

  • a plurality of receive coils, each of the plurality of receive coils configured to generate a respective voltage signal from a wireless magnetic field generated by a field generator; and

    a processor configured to;

    reduce a first set of data indicative of the respective voltage signals generated by the plurality receive coils to a second set of data that is substantially constant regardless of relative rotation between the plurality of receive coils and the field generator,determine a plurality of candidate positions based on comparing the second set of data to a plurality of first sets of stored data mapped to stored positions of the vehicle relative to the field generator,identify a plurality of second sets of stored data using the determined plurality of candidate positions, wherein the plurality of second sets of stored data are mapped to stored positions and orientations of the vehicle relative to the field generator, anddetermine a position and an orientation of the vehicle with respect to the field generator based on comparing the first set of data with the plurality of second sets of stored data.
