The present invention relates to a location system, for locating at least one object within a predefined cell, comprising at least first and second receivers (A, B, C, D), first and second transmitters respectively, including first and second internal clocks (rxA, rxB, rxC, rxD), the receivers, the transmitters respectively, having known locations, a transmitter, a receiver respectively, worn by the object and designed to communicate by means of signal exchanges with the receivers, the transmitters respectively, electronic circuits designed to compute a position related information of the object based on the signal exchanges, at least two reference transmitters (1, 2, 3), two reference receivers respectively, arranged to carry out a calibration operation of the first and second internal clocks, the system being characterized by the fact that it comprises a support adapted to link the two reference transmitters (1, 2), two reference receivers respectively, to each other, the support being configured such that it may be set at least in a first calibration configuration in which the two reference transmitters (1, 2), two reference receivers respectively, have a relative distance (dtx1/tx2) with respect to each other which is, a priori, known for the purpose of carrying out the calibration operation.
