ABSTRACT:
The system comprises a mobile device mounted (2) on each moving body, a fixed receiving antenna (3) and means for processing (4) the identification signals emitted by the mobile devices (2). The frequency of these identification signals is representative of the respective moving bodies. In addition, a transmitter (22) is provided to send the devices (2) a control signal that serves, on the one hand, to allow power supply to be applied to means for generating the identification signals and, on the other, serves as reference signal for those means, which do not have their own time base. This system is particularly well suited to the timing of automobile races.
