1. A system for positioning a vehicle over a wireless charging station, said system comprising:
- a wireless charging station equipped with a base wideband transceiver (UWBX);
a first UWBX configured to be installed on a vehicle;
a second UWBX configured to be installed on the vehicle; and
a controller configured to determine a location of the wireless charging station relative to the vehicle based on a first distance between the base UWBX and the first UWBX, and a second distance between the base UWBX and the second UWBX, wherein the controller is further configured determine reference distance between the first UWBX and the second UWBX as part of an auto-calibration process.
