US Patent 8698530 High precision synchronisation method and system

Method of synchronizing clocks between a first reference clock and a second clock to be slaved on the frequency of the reference clock, the two sharing a common clock, this method comprising the following steps:calculation of the integer part of the timestamp using the reference clock and the common clock;generation of a system clock local to the reference clock;calculation of the phase shift between the system clock signal and the reference clock signal;calculation of the phase shift between the system clock signal and the common clock signal;calculation of the decimal part of the timestamp;sending of the decimal timestamp to the second clock;slaving of the second clock using the common clock and the timestamp received.
