The embodiment of the invention discloses a UWB-based satellite signal-free area positioning system. The system comprises a plurality of logistics points arranged in a park, logistics point servers deployed at the logistics points, and UWB positioning tags arranged at the front ends of unmanned logistics vehicles; wherein each logistics point is provided with a plurality of UWB positioning base stations, and the UWB positioning base stations receive data packets sent by UWB positioning tags; the logistics point server is used for resolving data received from each UWB positioning base station to obtain vehicle position information corresponding to each UWB positioning label; the beneficial effects are that the UWB positioning label is arranged at the front end of the unmanned logistics vehicle, a plurality of UWB positioning base stations are additionally arranged at each logistics point, and the deployed logistics point server side is used to calculate the clock deviation of the synchronization signal, thereb
