Abstract: A method for locating a mobile element in a predetermined zone, including supplying power to an on-board module in the mobile element, where the on-board module includes an electronic circuit and an on-board coil, generating a locating signal by the electronic circuit and transmission of the locating signal via the on-board coil, picking up the locating signal by receiver coils on a support in proximity to the predetermined zone, each of the receiver coils configured to pick up the locating signal when the mobile element is in proximity, and determining a location of the mobile element in the predetermined zone by detecting a signal level on the support in the form of an array by a processing unit connected to the support. The electronic circuit and the on-board coil constitute an RLC circuit that oscillates, generating the locating signal by sudden interruption of the current through the on-board coil.
