Sub-cm 3D Real-Time Location System Prototype For Smart Factories, Logistics, Underground Mining and Digital Construction — The project focus is to convert the prototype Commercial Off The Shelf (COTS) proof of concept, which is limited to the audible range (up to 20 kHz) into a engineered rapid prototype operating in the ultrasonic frequency range.  Two units require engineering - beacons installed in known locations that transmit the ultrasonic signal, and trackers that receive beacon ultrasonic signals to compute position of a tagged asset.
