In one aspect, an apparatus for determining alignment information of a vehicle is disclosed, the vehicle comprising an antenna circuit configured to modulate one or more electrical characteristics of the antenna circuit. The apparatus comprises multiple sensor circuits configured to generate multiple magnetic fields. At least one sensor circuit may be configured to sense the modulated electrical characteristic of the antenna circuit when the antenna circuit couples to the at least one sensor circuit via one of the magnetic fields. The apparatus may further comprise a controller circuit configured to determine alignment information of the vehicle based on the sensed modulated electrical characteristic.
