Abstract
A positioning system comprises a set of pseudolites distributed in a confined area, said pseudolites transmitting positioning signals characterized by their time desynchronization and their apparent Doppler frequency, said time desynchronization and/or said apparent Doppler frequency of the positioning signals transmitted by the pseudolites being configured so that there is no ambiguity concerning the location of the correlation peaks P, P, P, P, Pin the matrix of ambiguities defined by the delay and the apparent Doppler frequency of the positioning signals acquired by the receiver.
