A motion-capture system containing a base-unit and one or more mobile-articles The base-unit contains two or more acoustic transmitters, each transmitting an acoustic signal, an RF transmitter transmitting a synchronization signal, and an RF receiver for receive timing data transmitted from the mobile-articles. The synchronization signal and the acoustic signals are transmitted synchronously, and the timing data contains time measuring information associated with time delay at the mobile-article, between the synchronization signal and the acoustic signals.
