Method of synchronizing a reference clock of a ground station and a clock of a remote system

A method of synchronizing a reference clock of a first ground station and local clock of a first remote system, in particular a moving body and notably a satellite, the reference clock signals being contained in reference bursts transmitted by the ground station and received by the first remote system, said bursts beginning with a recognition word, the method including:

• a) acquisition in a first loop of preliminary synchronization between said reference bursts received by the first remote system and bursts generated by the first remote system and synchronized with the local clock,
• b) detection of the recognition word of the temporally synchronized reference bursts received by the first remote system and generation after detection of said recognition word of a time window containing a given number N of pulses of said reference clock,
• c) acquisition of the average phase of said pulses received from the reference clock in the time window and comparison with the phase of the local clock, and
• d) in a second loop, synchronization of the phase of the local clock with said average phase to achieve said synchronization of the local clock.
