Beschreibung
Zusammenfassung:	The invention discloses an ultra-wideband positioning method. The ultra-wideband positioning method comprises the following steps of S1, arranging a plurality of UWB positioning tags in a tunnel, wherein the UWB positioning tags transmit signals according to a certain frequency; S2, continuously communicating each UWB positioning tag with a nearby anchor point, and sending the distance value to aUWB positioning base station arranged in the tunnel through a UWB channel; S3, after the UWB positioning base station receives a signal, carrying out bidirectional signal transmission with the UWB positioning tags, and transmitting a data packet to a positioning server through a data link; S4, carrying out decompression processing on each received data packet by a positioning server to construct atemporary position information list; and S5, calling a weighted least square method for positioning resolving by the positioning server, and constructing a real-time updated position information list. According to the method,
