Abstract: This invention refers to a synchronization method of a remote unit from a SPS timing signal (SPS) produced in a local unit. The SPS timing signal (SPS) is in the form of successive pulses (1) which are produced from signals received from satellites. The SPS signal (SPS) is asynchronous with respect to the system clock, that is, the reference clock defined between the local unit and the remote unit has no initial relationship with the SPS signal (SPS). The invention is characterized in that it includes the following steps: calculation in the local unit of an information (“10011010”) representing the number of local clock cycles occurring from the appearance of a pulse (1) until the moment (SL) when this information is injected into the data stream (FR); and generation in the remote unit of a synchronization signal related to the SPS signal, depending on this information (“10011010”).
