METHOD FOR LOCATING MOBILE DEVICES IN A COMMON FRAME OF REFERENCE

In a method for locating mobile devices, a trajectory (T, T) is reconstructed modelling a movement made by each mobile device during which the mobile device carries out measurements of an indicator linked to the distance separating it from access terminals (B-B) to a communication network. From these measurements, the locations of the terminals are calculated in a frame of reference linked to each mobile device. A procrustean analysis is then performed to determine, for each mobile device, a geometric transformation that transforms the locations of the terminals in the frame of reference linked to the mobile device into locations transformed in a common frame of reference. From this determination, the location of each terminal transformed in the common frame of reference is superimposed with a location of the terminal in the common frame of reference. Finally, the corresponding geometric transformation is applied to the trajectory of each mobile device.
