Abstract
A synchronization system for an acoustic signal-based positioning system is provided that generates a magnetic field as a synchronization signal. The magnetic synchronization signal is transmitted by a transmitter of the positioning system and received by the receiver of the positioning system. The receiver may include a magnetic synchronization signal receiver that may receive the magnetic synchronization signal on a same acoustic channel as an acoustic positioning signal. Moreover, the magnetic synchronization signal receiver may be a component already present in the receiver and capable of receiving a magnetic synchronization signal.
