Abstract

The invention relates to the technical field of wireless communication network positioning, and in particular relates to a passive positioning system based on ultra wide band (UWB) and a positioning method thereof. The positioning system comprises more than three positioning base stations and a UWB positioner which comprises antenna, a UWB receiver, a high-definition clock, a positioner data processing unit and a positioning engine; the positioning base station comprises a base station code ID generating unit, a time synchronization unit, a data processing unit, a UWB transceiver, a high-definition clock and an antenna. According to system and method, the positioning is performed by combing positioning technologies such as the extremely narrow pulse UWB signal and TDOA, the high-definition positioning independent of the horizontal and vertical direction of the external communication network is achieved, the positioning problem in the area with poor satellite or communications signals is solved, the system and method can be widely applied to indoor and outdoor working environments, particularly enclosed environments such as civil defense, disaster relief and other emergency sites with interrupted signals, and tunnels.

Description

technical field [0001] The invention relates to the technical field of wireless communication network positioning, in particular to an ultra-wideband-based passive positioning system and positioning method. Background technique [0002] The global satellite positioning system is widely used for outdoor positioning, but it cannot provide satisfactory positioning accuracy for indoor environments. In addition, people's demand for indoor positioning systems is also increasing day by day. It is necessary to use accurate indoor positioning information to achieve efficient management of available space and inventory materials, and to track firefighters in dangerous areas. Therefore, improving the positioning accuracy and stability of the indoor environment, reducing system complexity, etc., and finally realizing the seamless connection between indoor and outdoor positioning systems has become a future research and development trend. [0003] At present, the technologies that indoo...
