A short range positioning system under development is described. A hybrid ultrasonic ? RF link is established between three or more transmitters of known positions and a multi-channel receiver fitted to a mobile vehicle. The described system exploits the enormous propagation speed difference between electromagnetic and sound waves to obtain synchronization without the need of precise (and expensive) clocks. Simulation and partial experimental results are presented
