A controller for controlling an autonomous vehicle. The controller comprises a reconfigurable intelligent surface (RIS) transceiver configured to receive RIS signals from a RIS device, a positioning signal receiver configured to receive positioning signals from a positioning signal transmitter, and a processor. The processor is configured to process the RIS signals to produce RIS data, process the positioning signals to produce positioning data, fuse the RIS data and the positioning data using a data fusion algorithm to compute a location of the autonomous vehicle, and control operation of the autonomous vehicle based on the computed location.
