Demonstrator of Time Services based on European GNSS signals: the H2020 DEMETRA Project
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
Experimental time dissemination services based on European GNSS signals: The H2020 DEMETRA project
DEMETRA aims to be a prototype of an European time dissemination service, based on the timing signal of the European Galileo system, adding particular features like - among the others - certification, calibration, or integrity, that could be of interest to a wide range of users belonging to different sectors as traffic control, energy distribution, finance, telecommunication, and scientific institutions. Nine time dissemination services are proposed. The paper will report about the development status and the first experimentation results of the system, showing potentialities and limits of the proposed time dissemination services, aiming to foster the exploitation of the European GNSS for timing applications
The H2020 european project DEMETRA: Experimental time services based on European GNSS signals
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
