Abstract

The embodiment of the invention provides a high-precision positioning system and a positioning method. The system comprises a positioning engine, a dual-mode synchronization unit, a dual-mode base station, a single-mode base station, a dual-mode positioning tag, a single-mode positioning tag, a low-power-consumption positioning tag and a communication link. The position data precision and the positioning configuration flexibility can be effectively improved.

Description

technical field [0001] The present application relates to the field of positioning, in particular to a high-precision positioning system and a positioning method. Background technique [0002] In recent years, UWB-based real-time positioning systems have been widely used in various industries to provide high-precision positioning services. Based on base stations with known locations, there are three mainstream positioning methods: [0003] 1) Signal angle of arrival method (Angle of Arrival, AOA), this method obtains the position information of the tag under test by obtaining the angle of arrival of the signal from the tag under test to two base stations. AOA positioning can not only determine the coordinates of nodes, but also provide the orientation information of nodes. However, the AOA ranging technology needs to configure a complex antenna system, and is easily affected by the external environment, so it is not suitable for large-scale positioning networks. [0004] ...
