A method for measuring the distance between a first and at least one second unit (10, 20) provided respectively with a UWB transceiver (11, 21) provided with internal clocks (16, 26), communication between the units (10, 20) taking place in time-division duplex mode according to a plurality of frames each comprising at least one time interval, counted cyclically from a first and a second time reference (T10, T20, T30), the method comprising the following steps: - transmission, by the first unit (10), of the first UWB signal (SIG10); - transmission, by the second unit (20, 30), of a second UWB signal (SIG20*, SIG30*) comprising an indicator linked to the reception time of the first UWB signal (SIG10); - determination, by the first unit (10), of the distance (D10-20) separating same from the second unit (20). |
