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
Bezpieczna i pewna synchronizacja czasu w ważnej infrastrukturze państwowej – ENERGETYKA. Wady synchronizacji opartej o odbiorniki GNSS i sieć Ethernet NTP/PTP
W latach 2015–2017 firma Elproma uczestniczyła w międzynarodowym projekcie DEMETRA Horizon 2020. Projekt dostarczył 9 nowych usług synchronizacji, wspierających wdrażany przez UE system GALILEO. Aby dobrze wykonać powierzone zadania, DEMETRA poprzedzona była licznymi badaniami rynku określającymi zapotrzebowanie przemysłu na usługi synchronizacji. Przeprowadzono na terenie UE liczne audyty techniczne wybranych systemów synchronizacji opartych o satelitarny system GPS i sieć Ethernet TCP/IP, a ich wyniki odsłoniły liczne niedoskonałości obecnych rozwiązań
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
The Horizon 2020 DEMETRA project: DEMonstrator of EGNSS services based on Time Reference Architecture
DEMETRA (DEMonstrator of EGNSS services based on Time Reference Architecture) is a project co-funded by the EU through the research and innovation programme 'Horizon 2020'. The DEMETRA project started in January 2015 and lasts 24 months. Based on the current practice of national metrological laboratories, identifying the additional necessities of the timing users, DEMETRA will define and develop a prototype of a European time disseminator, based on EGNSS. Nine different time services are proposed for demonstration by consortium partners. The DEMETRA partnership, including Scientific Institutions, GNSS Industries, and a Service Provider cover the different faces of the project, including an analysis of commercial potential in terms of market and business development
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 European project DEMETRA:Demonstrating time dissemination services
Recently an European Consortium of 15 partners from 7 different countries, started to work on a research project, DEMETRA (DEMonstrator of EGNSS services based on Time Reference Architecture), funded by the European Union in the frame of the Horizon 2020 program, aiming to develop and experiment time services based on the European Global Navigation Satellite System (GNSS). 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 certification, calibration, or integrity, that could be of interest to some specific users like traffic control, energy distribution, finance, telecommunication, and scientific institutions
The European project DEMETRA, timing services based on European GNSS: First experimental results
The H2020 research project, DEMETRA (DEMonstrator of EGNSS services based on Time Reference Architecture) is funded by the European Union and aims to develop and test several time services based on the European Global Navigation Satellite System (GNSS) and introducing important new features such as certified time stamping, improved accuracy, or integrity, not yet provided by GNSS systems. The demonstrator has been successfully assembled at INRIM premises by the end of February 2016, and it will be tested with two validation test campaigns. The first closed loop test finished in May 2016, the first experimental results to validate the time services performances are here reported. The second test campaign will be conducted in a realistic case at user premises, to test the real advantages and feasibility of the proposed time services
Time dissemination services: The experimental results of the European H2020 DEMETRA project
In 2015 and 2016 a European Consortium of 15 scientific and industrial partners from 8 different countries collaborates on the DEMETRA (DEMonstrator of EGNSS services based on Time Reference Architecture) project, 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. The project aims at being a prototype of an European time dissemination service, based on the timing signal of the 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, telecom, and scientific institutions. Nine time dissemination services are proposed. The project is under experimentation since March 2016, we report the first experimentation results of the system, showing potentialities and limits of the proposed services, aiming to foster the development and possibly standardization of the time dissemination services
