ERSAT GGC First Exploitation Meeting

ERSAT GGC 1st Exploitation Meeting On the 6th of June, the ERSAT GGC project, coordinated by RFI and funded by GSA held an exploitation meeting with the participation of experts from the GSA, ESSP, Shift2Rail JU and the European Space Agency (ESA) as well as their on-going projects of STEMS and CAPRESE. ERSAT GGC consortia presented the main outcomes of the work packages related to the Enhanced ERTMS Architecture for the introduction of the GNSS technology and the Virtual Balise concept and the Safety and Hazard Analysis as well as the standards assessment of the Enhanced ERTMS Architecture for the introduction of the GNSS technology. The focal point of the workshop was the ‘Enhanced ERTMS Architecture for the introduction of the GNSS technology and Virtual Balice’ concept, which seeks to define the inputs for the evolution of the ERTMS standard to integrate GNSS technology.

This concept aims to create cost and efficiency benefits as it could substantially decrease the use of the physical balises normally utilized for train positioning. The Safety and Hazard analysis of the Enhanced ERTMS Architecture as well as the assessment of its compliance with the standards and norms were also discussed with the participants. Due to the potential complementarity between ERSAT GGC and CAPRESE/STEMS initiatives funded by ESA , NSL presented, during the meeting, their frameworks, scope, goals and structure.

ERSAT-GGC project presented at EU-US Working Group C on Next GNSS Generation

The ERSAT-GGC project was presented at the last meeting of the European Union and the United States Working Group C (EU-US WG-C) on next GNSS generation on the 20-23 May 2019 at the German Aerospace Center in Oberpfaffenhofen.
Omar Garcia Crespillo, from DLR (partner of the project), introduced the overall goals and context of ERSAT GGC on behalf of the consortium and showed the last developments within WP4 – Track Survey and Track Area Classification. The project was presented at both the Service Evolution and the Resilience Subgroup of the EU-US WG-C. For more information about the presentation, please contact Omar Garcia Crespillo.

During the time from the 20th until the 31th of May, one of the foreseen ERSTA_GGC measurement campaigns took place in the Spain line nº528, this line runs through the provinces of Badajoz and Córdoba, in the frame of WP4 of ERSAT-GGC project based on the characterization of a low-traffic regional line.

It is considered that the implementation of modern signalling system in this type of lines based on GNSS technology could be an interesting new approach for increasing the line performance, reliability and safety.

The data collected during the measurement campaign collects information to evaluate areas in the line in terms of multipath, satellite visibility and interferences, with the aim of classifying them as suitable/not suitable for placing virtual balises. The selected track section of 94 km is between Almorchón and Alhondiguilla stations. The selected rolling stock is a laboratory train from Adif (Talgo BT-02) which for ERSAT-GGC project, has been equipped with suitable GNSS devices to register all the required data that will be analyzed by the toolset developed within the project. The duration of 10 days of dynamic testing was based on covering different locations of the satellites in the orbits and running under different epoch conditions.

In the preparation and execution of the measurement campaign ADIF, INECO, IFFSTAR, DLR, and CEDEX were involved.


ERSAT GGC measurement campaigns took place in the Italian line Cagliari-San Gavino in Sardinia

During the week from the 8th until the 13th of April, one of the ERSAT GGC measurement campaigns took place in the Italian line Cagliari-San Gavino in Sardinia.
The aim of the collection of GNSS measurements is to perform the track area classification with respect to the presence of GNSS threats (i.e. multipath, NLOS and Interference), which is the main goal of WP4. During the measurement campaign week, where over 1700 km of data were recorded, some important requirements were taken into account in the definition of train runs schedule considering time repeatability and an adequate distribution of the train runs to cover different time slots along the day, including train runs during the night.

In the preparation and execution of the measurement campaign RFI, Trenitalia, DLR, Radiolabs and Hitachi Rail STS were involved. CEDEX and ADIF also participated to the campaign and are preparing together with INECO the next measurement campaign in Spain.


On 19th March 2019 partners of the project participated in the Event SPACE FOR INNOVATION IN RAIL organized by GSA, Shift2Rail and ERA, dedicated to the GNSS applications for rail. During the event Massimiliano Ciaffi, project coordinator of ERSAT GGC presented the progress of the project together with the main results already achieved and the next steps until the end of the project.

The presentation from Mr. Ciaffi is available here.
