Abstract
The invention relates to a method of synchronizing a reference clock of a first ground station and a local clock of a remote system, in particular a satellite. It includes:a) acquisition in a first loop of synchronization between reference bursts received by the remote system and generated bursts synchronized with the local clock,b) detection of the recognition word of the reference bursts received by the first remote system and generation of a time window containing N pulses of the reference clock,c) acquisition of the average phase of said pulses and comparison with the phase of the local clock, andd) in a second loop, synchronization of the phase of the local clock with said average phase.The method can be reiterated to synchronize a second ground station with the first one via the remote system.
