1. A system for real time acquisition and processing of data pertaining to the position and/or physical performance of one or a multitude of persons in motion on a field, in particular athletes in motion on a game field characterized by the fact that it includes:

  • (a) devices used to acquire in real time the instantaneous individual positions of every person in the field, said devices comprising miniaturized radio frequency transmitters carried by said persons and a set of at least three goniometric receivers tuned successively to the frequency of said transmitters so as to sweep all of the transmitted frequencies as a function of time and to detect several times per second the instantaneous position of every transmitter on the field through triangulation based on the directions from which every transmitter transmits;

    (b) devices used for the digital processing associated with said acquisition devices to determine a set of digital Values which are representative of the physical performances of said persons based on said instantaneous position information;

    (c) interface devices connected to said digital processing devices responsible for preparing the digital Values which are representative of the physical performances as well as for their graphic representation.
