The invention relates to a positioning system and a method for determining the position of moving objects and persons using a GSM network, whereby: a) a GSM mobile radio unit is used to determine available stations and stationary (GSM) radio stations in the receiving point, the cell data thereof and the Ta-values being determined at least three times, b) Ta values are compared with each other to check reproducibility and are rejected when a tolerance threshold is exceeded, c) Ta values, which lie within the tolerance threshold, and their cell values representing position information data for updating a reference databank are fed to an evaluation and processing unit; d) and/or using the evaluation and processing unit of the reference data updateable position data is converted into position coordinates of the GSM mobile radio unit and applied. |
