IR-UWB Location Positioning Method and System with Wireless Synchronization

The present invention is an ultra-wideband wireless impulse communication using an impulse signal of less than nano-sec in the time domain to synchronize the beacons to increase the accuracy of positioning according to the TDoA (Time Difference of Arrival) scheme It relates to a wireless positioning method and system that can be implemented. In the wireless positioning method according to the present invention, a master beacon transmits a first sync pulse and a second sync pulse at an operation cycle of a positioning lock clock of the master beacon, and at least one slave beacon and the first sync pulse and the second sync pulse. After synchronizing the positioning lock clock of the slave beacon with the positioning lock clock of the master beacon using the receiving time difference of the sync pulse, based on the receiving time difference of tag pulses received in each of the master beacon and the at least one slave beacon. The position of the tag can be calculated. Ultra Wideband, Radiodetermination, Time Difference of Arrival (TDoA), Synchronization
