Abstract

The invention relates to the field of ultra wide band wireless communication, and discloses a positioning system based on an ultra wide band. The system comprises: at least three base stations and a client, the base stations are synchronous in completion time, and the base stations adopt a time division multiple access technology to send ultra wide band signals with positioning information; and the client receives the ultra wide band signals of the base stations, analyzes a pseudo range between the client and the base stations and the position information of the client, and realizes solving ofthe position coordinates of the client itself. The invention further discloses a positioning method based on the ultra wide band. According to the invention, the problems of high complexity, limitedclient capacity, low positioning precision and the like of an ultra wide band positioning technology are overcome, easy implementation of the positioning system is improved, and the client has no capacity limitation and is high in positioning precision.

Description

technical field [0001] The invention relates to the field of ultra-wideband wireless communication, in particular to a positioning system and method based on ultra-wideband. Background technique [0002] The current positioning system based on UWB technology mainly uses two-way ranging method (TWR, Two-Way Ranging) or one-way ranging method (OWR, One-Way Ranging) to measure the distance between the user terminal and the base station to achieve positioning. The advantage of the two-way ranging method is that it relatively reduces the time synchronization requirements between the base station and the user terminal; the advantage of the one-way ranging method is that the number of user terminals can be unlimited. [0003] However, the two-way ranging method requires the base station and the user end to transmit and receive UWB signals respectively, such as figure 1 In the positioning system shown, first, multiple base stations and user terminals 0 transmit and receive ultra-wi...
