The European Geostationary Navigation Overlay Service (EGNOS) is Europe's first venture into satellite navigation. To support its uptake across all market segments, the European Satellite Services Provider (ESSP), in collaboration with the European GNSS Agency (GSA), organized an annual EGNOS Service Provision Workshop.
Since its launch, the workshop has evolved into an annual event for EGNOS Stakeholders, Users and App Developers. The event is now held over two days and involves debates, showcases, presentations and success stories. The 2014 edition of this Workshop was held from October 7 – 8 in Lisbon, Portugal. Around 170 participants, representing more than 26 countries, were in attendance.
GSA Executive Director Carlo des Dorides provided the opening address to the delegates. “This workshop is an excellent opportunity to come together, exchange experiences and look ahead,” he said.
ESSP Chief Thierry Racaud agreed, adding: “it is encouraging to see so many EGNOS users within this fora, sharing their experiences and projects with all of us,” he said. “The growing number of GNSS stakeholders makes our job even more challenging, requiring us to put all our effort in promoting the use of EGNOS in the different domains of applications, while continuing to deliver the service in an efficient and safe manner.”
“The future of EGNOS is very positive,” added Des Dorides. ”In the medium term we will have a fully deployed version three, which will bring an extension to the system’s geographic coverage, along with dual frequency and increased accuracy.”
He noted that these expansions will result in a wider adoption of EGNOS, moving beyond aviation and more heavily into, for example, maritime and rail.
“Today we are still facing difficult economic times and the key word we keep hearing is ‘innovation, innovation, innovation’,” he said. “This is what EGNOS is and what it enables – innovation.”
EGNOS Service Update
The first day of the event was devoted to providing the latest updates on EGNOS services and status, along with a ‘state-of-play’ of the EGNOS market. Jean-Marc Pieplu, GNSS Exploitation Program Manager (GSA), and Gian-Gherardo Calini, Head of Market Development (GSA), provided the introductory session and EGNOS Program Update.
According to Pieplu, the key exploitation objectives include:
• The delivery of continuous and safe signals and services
• Maintaining and renewing space and ground infrastructure
• Improving services
• Enabling the use of EGNOS
• Developing EGNOS market adoption
“With EGNOS Version Three we will add to this list several new opportunities,” he said. “Specifically, we will focus on designing new services and standards in the maritime and rail sectors, along with extending coverage to neighbouring countries, including the Mediterranean region and the Ukraine.”
Adding to this, Calini noted that each market sector has a unique value chain, “so we must adapt our exploitation strategy for each sector, and the key to doing this is to ensure people are convinced of the importance of EGNOS to their specific sector,” he said.
Calini noted that the GSA was dedicated to its user driven market approach: “The implementation of market oriented actions enables EU industry and citizens to benefit and helps achieve EU strategic objectives,” he said. “Users do not discriminate as to services or systems, thus we must continue to focus on vertical market segments.”
So where do we want to be by 2020?
According to Calini, on the aviation side he expects to see more than 440 EGNOS-based LPV approaches implemented. In maritime, EGNOS will be adopted as a complementary system to DGNSS infrastructure, and the rail sector will benefit from E-GNSS based positioning. E-GNSS technology will provide multipurpose receivers in every vehicle, and the agricultural sector will see ENGOS as the preferred technology for accomplishing precision agriculture.
Success in the sky
To highlight how these 2020 goals can be achieved across the various market sectors, the Workshop focused on the aviation sector as a case study in success. The afternoon of the first day consisted of various presentations regarding successful EGNOS implementation stories in aviation, debriefed by skyguide, DSNA, Aviation Southwest and VLM. The participants particularly appreciated a presentation from the US Federal Aviation Administration (FAA).
According to the presentations, there are presently more than 440 EGNOS-based LPV procedures planned by 2018. For their part, GNSS devices reach 90% penetration in the installed bases as an enabler of Performance Based Navigation.
However, if everything that is planned is to be achieved by 2020, several things must happen. First and foremost is fostering EGNOS adoption through enablers/tools/methodologies to facilitate LPV implementation. This includes increasing the availability of efficient avionics solutions and supporting operators in getting both equipped and certified with EGNOS avionics by, for example, including EGNOS in training syllabus, following ongoing European Aviation Safety Agency (EASA) work and increasing helicopter adoption.
Second is getting ready for LPV-200 capability, followed by exploring E-GNSS potential for communication, navigation and surveillance for all flight phases. The third point made is to exploit advanced operations using GNSS as an enabler (e.g. 4D) and, lastly, to get ready for multi-constellation/multi-frequency solutions.
Looking towards maritime
Other EGNOS applications outside of the aviation world were the main subject of the Workshop’s second day. Primarily the discussions focused on EGNOS land and maritime applications. Accordingly there were presentations from UNIFE, Telespazio, RSOE, TOPCON and the General Lighthouse Authority of the UK & Ireland.
The EDAS service for added value applications was also a main theme of the day. The GSA and ESSP also explained the actual status of EGNOS markets, and the actions that are being taken for further EGNOS adoption in multimodal domains.
Specifically as to maritime, GSA, European Commission and European Space Agency efforts are focused on getting EGNOS adopted as a complementary system to DGNSS infrastructure, thus ensuring its role in the future e-Navigation concept. Galileo is in the process of being recognized by International Maritime Organization (IMO) as part of World Wide Radio Navigation System.
The goal to be achieved by 2020 is to have Galileo for navigation in ocean, coastal and restricted waters using double frequency receivers and RAIM (penetration in Rx similar to GLONASS). Differential Galileo (incl. RTK) should be available for high precision operations in ports along with Galileo-SAR return link capability adopted in beacons and EGNOS complementing IALA beacon infrastructure providing integrity information.
To achieve this, Galileo has to be recognized by IMO as part of the WWRNS. The new IMO performance standards for multi-system ship borne navigation receivers, currently in preparation, will enable the inclusion of EGNOS once the maritime SBAS standards are ready. Differential Galileo needs to be included in Maritime standards. This requires a promotion campaign of Galileo/SAR return link capability to beacon manufacturers and users, as well as launching an EGNOS/EDAS demonstration project and awareness campaign with the support of EMRF/IALA.
“This workshop is an excellent opportunity to come together, exchange experiences and look ahead.”
