A Work Plan for the European Railway Traffic Management System (ERTMS), published by the European Commission in May this year, lists satellite positioning as one of the game changing technologies underpinning future evolutions of the system and a key element to be included in future Technological Specifications for Interoperability (TSI).

The ERTMS is a major industrial project that aims to make rail transport in Europe safer and more competitive. As a safety system, the ERTMS enforces train compliance with speed restrictions and signalling and consists of equipment installed both on trains and along the railway tracks.

According to the latest Work Plan, the ERTMS will become the backbone of railway digitalisation in Europe, allowing for the introduction of new technologies, including but not limited to automatic train operation, satellite positioning and other technologies capable of optimising rail performance and capacity. 

Positive cost benefits

“In light of the important role that GNSS positioning will play in the system, the GSA recently conducted a cost-benefit analysis for virtual balises, one of the possible technical solutions for the ERTMS,” said Daniel Lopour, Market Development manager for rail. “This analysis showed that there is a positive cost/benefit ratio, both for railway infrastructure managers and for the industry as a whole,” he said.

The GSA report found that, to make a good economic case, a rail line must be in a location that enables the deployment of a large number of virtual balises, when physical balises have not yet been deployed. The cost of balise maintenance also has an impact on the attractiveness of the project: the maintenance cost per physical balise should be high to allow for more cost savings.

One of the guiding principles for the future evolution of the ERTMS, including the revision of the Control Command and Signalling (CCS) Technological Specifications for Interoperability (TSI) planned for 2022, is to ensure that the TSI will deliver significant business case improvements for the railway sector. For this to happen, and to achieve higher capacity and better performance, the ERTMS game changers should be included in the TSI revision.

Investing in the future

Within the framework of Horizon 2020, the GSA and the Shift2Rail Joint Undertaking have been investing to ensure that Galileo and EGNOS can support localisation objectives within the ERTMS. R&D projects such as ERSAT, STARS and X2RAIL2, for example, have helped to analyse the rail environment, define the necessary architecture of the train positioning subsystem and provide the first operational pilots, transferring early results to European tracks.

To support the ERTMS Work Plan the GSA, together with European Space Agency (ESA), is also actively supporting railway companies, infrastructure managers and the EU railway industry from the technical perspective regarding the different GNSS services needed for fail-safe train localisation. 

The GSA will continue to collaborate with Shift2Rail and the European Railway Agency on the necessary changes to ERTMS and the relevant European GNSS services, with the ultimate goal of delivering GNSS-based localisation-related efficiency benefits to the future evolutions of the ERTMS.

Dňa 3.7.2020 sa v Nýrovciach konal pracovný seminár za účasti ministra pôdohospodárstva

Over 200 participants from 32 countries took part in the fourth GNSS Raw Measurements Task Force Workshop, held online on 27-28 May 2020. At the workshop, participants had the opportunity to learn about progress around the use of raw measurements in Android devices and to benefit from the experience of the GSA’s Raw Measurements Task Force.

By sharing knowledge and experience around raw measurement use, the GNSS Raw Measurements Task Force Workshops increase the global understanding of raw measurements and advance the science and practice of implementing raw measurements in apps and devices. This year the event was online, with lively discussions held over the two days of the workshop.

Sharing knowledge

In his keynote presentation on May 27, Google`s Frank Van Diggelen spoke about updated Google tools for logging and analysing GNSS measurements, with new features already available in GnssLogger, such as logging in RINEX format or logging of other sensor data, or in GNSS Analysis software - such as new PVT filters or “select satellite for position”. Additional features (e.g. antenna phase centre offset), to be available with the Android 11 release in the third quarter of this year, were also highlighted.

Discussions at the workshop confirmed that GNSS raw measurements are increasingly used in educational and scientific projects around the world, leading to increased knowledge and interest in GNSS technology and better implementation of GNSS within smartphones. In addition, there is already a growing body of evidence that sub-meter positioning is feasible in real-time with current smartphones when using RTK and other techniques. So, it is just a question of when, rather than if, it will become widely used. What’s more, test results from dual frequency chipsets presented at the workshop showed Galileo’s added-value in improving accuracy by reducing multipath.

“The Raw Measurements Task Force Workshop allows all stakeholders interested in raw measurement use to share their knowledge and experience and to ensure that the benefits of GNSS raw measurements are enjoyed by as many people as possible,” the GSA’s Head of Market Development Fiammetta Diani said in her welcome address.

Over 20 interesting presentations

The day concluded with presentations from Airbus (Tomasz Lewandowski) and ESA (Xurxo Otero) showing test results with dual-frequency smartphones and evaluation kits. There were also presentations from Qascom (Carlo Sarto) on future OS-NMA use in smartphones; the GSA (Joaquin Reyes) on how raw measurements improve the digitalisation of CAP controls; EC (Katarzyna Porzuc) on GNSS raw measurements in the context of ensuring caller location in emergency communications; and JRC (Maria Angeles Aragon) about the NeQuick-G algorithm.

On the second day of the workshop, when another eleven contributions were presented, Rokubun CTO Miquel Garcia-Fernandez spoke about WiFi RTT (Round Trip Time) measurements as the GNSS companion for Indoor Positioning. Regarding the workshop, he said: “After four editions, the GSA Raw Measurements Task Force has matured and has become a reference to be up to date in recent advances regarding GNSS data processing for mobile devices.”

“Its participants, from public institutions, academia, big companies as well as SMEs provide an updated and relevant snapshot of the GNSS community developing new location technology for smartphones,” Garcia-Fernandez said.

Join the Task Force

The GNSS Raw Measurements Task Force is dedicated to promoting a better and wider use of GNSS raw measurements. 

Since its launch in 2017, the Task Force has expanded from a handful of experts to a community of over 100 agencies, universities, research institutes and companies. Membership is open to anybody interested in GNSS raw measurements. To join the Task Force contact: market@gsa.europa.eu.
