1. A method of operating a vehicle-mounted ranging system having a communication transceiver configured to wirelessly communicate with at least one external communication transceiver, a plurality of ultra-wideband (UWB) transceivers configured to transmit and receive ranging pulses to and from a UWB transceiver of the at least one external communication transceiver, and a controller interfaced with the communication transceiver and the plurality of UWB transceivers, the method comprising:
communicating wirelessly with the at least one external communication transceiver to schedule transmission of ranging pulses between the plurality of UWB transceivers and the at least one external communication transceiver by way of the communication transceiver under control of the controller;
configuring by way of the controller the plurality of UWB transceivers with the schedule of the transmission of the ranging pulses; and
calculating by way of the controller ranges between each of the plurality of UWB transceivers and at least one UWB transceiver of the at least one external communication transceiver based upon time-of-arrival of ranging pulses transmitted between the plurality of UWB transceivers and the at least one UWB transceiver of the at least one external communication transceiver.
