    摘要: A method for synchronizing at least one master loop (10) with one or more disciplined generators (11), comprising the steps of:
    (a) sending (12) a reference time signal (30) from a master loop (10) to a satellite path (5);
    (b) receiving (14, 16), on the part of the master loop (10), the reference time signal (30) retransmitted by the satellite path (5) in order to use the signal (30);
    (c) receiving (15, 22), on the part of each one of the one or more disciplined generators (11), the reference time signal (30) retransmitted by the satellite path (5);
    (d) modifying the local time speed so as to synchronize the transmission of all the signals transmitted by the disciplined generators (11) to other users with the reference time signal (30) transmitted by the master loop (10) in step (a).
