Abstract

This system includes a ground ATC and an on board ATC, which is switched from an “active” mode toward a “standby” mode and vice versa by a wake-up unit. In the “standby” mode, only the following components remain powered: odometry device; a main computer; a radio communication device between the on board ATC and the ground ATC; the wake-up unit. The main computer is programmed so as, in the “standby” mode, to verify that the movement of the train measured by the odometry device from the switching from the “active” mode to the “standby” mode is zero and, in the affirmative, to send the ground ATC an instantaneous position of the train using the radio communication device.
