Abstract:
1. A location-beacon receiving apparatus for receiving a location-beacon from a transmitting apparatus, comprising a first-signal receiver for receiving a first-signal containing synchronization information; a second-signal receiver for sequentially receiving second-signals; a synchronizing unit configured to synchronize with the transmitting apparatus utilizing the synchronization information contained in the first-signal and obtaining a synchronization timing; an order identification unit configured to indentify a transmission order for the respective second-signals received by the second-signal receiver based on the synchronization timing; a TOA acquisition unit configured to acquire a TOA information sequence corresponding to the respective second-signals based on the transmission order of the respective second-signals identified by the order identification unit; and a position calculation unit configured to calculate the position of the receiving apparatus based on the positions of the transmitting sources of the respective second-signals received by the second-signal receiver and the TOA information sequence acquired by the TOA acquiring unit.
