Abstract: An on-board device is configured for reading a telegram of a balise installed at a point along a route followed by a guided vehicle in which the on-board device is to be installed. The on-board device includes a receiver having an antenna for picking up the telegram transmitted by the balise and delivering a reception signal to a processing unit. The processing unit is configured for processing the reception signal in order to read the telegram sent by the balise. A test component is configured for adding a test signal to the reception signal before its processing by the processing unit. The test signal is configured to act as a noise for limiting a sensitivity of the receiver, making it therefore impossible to read a cross-talk signal. A method for protecting the on-board device from cross-talk is also provided.

Abstract: A vehicle is supplied by a first electrical energy storage unit on board the vehicle, and a ground electrical network providing an energy supply by application of a supply voltage through electrical distribution. The first energy storage unit is controllable under a generator regime or a receiver regime.
