Positioning system and method

The invention provides a positioning system and method, and belongs to the technical field of positioning. Comprising at least N signal sending units, at least M data transmission units and an analysis unit, each signal sending unit comprises a positioning base station, each data transmission unit comprises a data transceiving unit, and the signal sending units and the data transmission units are alternately arranged and connected end to end; and the positioning base station performs signal transceiving with the terminal equipment through the data transceiving unit of the data transmission unit, and generates transmitting characteristics and receiving characteristics of each signal. The analysis unit receives the sending characteristics and the receiving characteristics sent by each signal sending unit and the corresponding identification of the target positioning base station and the identification of the terminal equipment, wherein the target positioning base station is a positioning base station for receiv
