A position offset between a primary coil and a secondary coil of an inductive power transfer pair is determined using a region classifier model and an absolute position model of an operational charging region between the primary coil and the secondary coil. During operation, radio signal information including magnitudes and phase differences is collected from respective radio receivers of a ground transceiver assembly and a vehicle transceiver assembly. The radio signal information and the region classifier model are used to determine whether the vehicle has entered or departed the operational charging region, and the radio signal information and absolute position model are used to determine absolute or relative offset positions of boresights of the primary coil and the secondary coil. A display provides an indication of the absolute or relative offset positions between the boresights of the primary coil and the secondary coil.
