Published a Technical Note on SFN network synchronisation
Radio and television single frequency digital broadcast networks (SFN - Single Frequency Network) must be synchronized, with time and frequency references (1PPS and 10MHz) common
and identical, in all respects, to all transmitters in the network. The easiest and cheapest way to obtain these references is based on the reception of signals coming from the GPS satellite network; however, many of the GPS receivers / synchronizers available are not suitable for this specific application because they can introduce, over time, de-synchronization of the SFN network and network disturbances impacting the viewer. The broadcast SFN application requires the GPS receivers / synchronizers to have special features that can be difficult to implement.
