SynchroNet Service Demonstration Results in Demetra H2020 Project: A Scalable High Performances Synchronisation Solution

Enrico Varriale and Quirino Morante

Abstract:	SynchroNet is a Thales Alenia Space Italia patented solution for a high performance, scalable and resilient time and frequency transfer system. The SynchroNet system addresses an arbitrarily large and topologically distributed network of nodes equipped with atomic clock(s) (ranging from inexpensive rubidium to high end oscillators like Active Hydrogen Maser) with baselines up to thousands of kilometers between any two nodes. SynchroNet uses GNSS (Global Navigation Satellite Systems) Signal in Space to implement a distributed approach of classical time transfer and complements this function with autonomous steering functions implemented at each node to cope with Signal in Space interruptions/disruptions. SynchroNet provides a complete set of service oriented functionalities around the core synchronisation capability, for this reason it can be suitable for a large range of application domains where synchronisation is required either in terms of accuracy or in terms of scalability or both. This paper will provide an overview of SynchroNet architecture and capabilities as well as its declination to the DEMETRA project and the demonstration campaign results of the core synchronization capabilities as verified by the DEMETRA Service Monitoring. DEMETRA (DEMonstrator of EGNSS services based on Time Reference Architecture) project is funded by the European Union in the frame of the Horizon 2020 program, aimed at developing and experimenting time dissemination services based on the European GNSS. DEMETRA project has received funding from the European GNSS Agency under the European Union’s Horizon 2020 research.
