| description | The invention discloses a TDOA-based positioning system, which comprises a master base station, a slave base station and a label, and is characterized in that the label is to-be-positioned equipment;the master base station and the slave base station send signals outwards in a broadcasting mode, clock synchronization of the label and the master base station is further achieved, TDOA measurement ofthe label is obtained through calculation, then quick positioning of the label is achieved in combination with a TDOA positioning algorithm, and the calculation complexity of label positioning is greatly reduced; and meanwhile, the label is positioned and executed locally, so that the problems of label capacity limitation and the like caused by insufficient bearing capacity of the server are avoided. The indoor positioning of the label is realized based on the downlink TDOA system, the calculation complexity of TDOA measurement can be greatly reduced, and the indoor positioning efficiency isimproved.
