During 2015-2016, a European Consortium of 15 partners from 8 different countries, developed the DEMETRA (DEMonstrator of EGNSS services based on Time Reference Architecture), a project funded by the European Union in the frame of the Horizon 2020 program. This project aims at developing and experimenting time dissemination services dedicated to specific users like traffic control, energy distribution, finance, telecommunication, and scientific institutions. Nine services have been developed. These services provide time dissemination with accuracy levels from millisecond to the sub-ns, and also additional services like certification, calibration, or integrity. Five of these services are based on the European GNSS. After a development phase (see PTTI 2016 presentation) the full DEMETRA system has been working during six months for demonstration. The paper will report about the experimentation results, showing performances and limits of the proposed time dissemination services, aiming to foster the exploitation of the European GNSS for timing applications.

“…The DEMETRA Project [1]- [3] was conceived to demonstrate the feasibility and the possible performance of time services mainly based, but not only, on the Galileo timing signal. During the last two years a demonstrator has been built for developing, testing, and validating time dissemination services in a realistic environment.…”

DEMETRA, the "DEMonstrator of Egnss services based on Time Reference Architecture", is an European Project funded by the European Union in the Horizon 2020 program. The main aim of the project was to develop and test a prototype of Time Service Provider based the European Global Navigation Satellite System (GNSS) providing innovative or improved time services based on different technologies and embedded in a modular architecture. The main innovative features are time certification, non-repudiation, integrity, reliability, resilience. The demonstrator has been developed and tested during the years 2015-2016. Nine different time services were developed and tested also in real environment at users premises. The paper reports the results of the experimental campaigns and the main lesson learned also by the trials with potential users.

“…Recent changes in financial market regulations, as well a growing demand from traders and service providers for more accurate time, have driven the development of commercial time services with sub-microsecond precision. Several National Metrology Institutes (NMI), including NRC, are currently offering or are developing such services [1,2]. The NMIs' advantages in providing time services are their expertise in time transfer and metrology, and the authority they have in their respective countries for the realization and dissemination of official time.…”

The demand for secure and accurate time has been growing in recent years in telecommunications, infrastructure, navigation and finance. The requirements are for traceable time with sub micro-second precision. Currently available methods have technical or reliability limitations in achieving this goal. The NRC Remote Clock product offers secure traceable time dissemination to a remote user. Our method achieves few tens of nanoseconds uncertainty and relies on a remote high quality clock that is controlled from the NRC main lab.
