WalkEGNOS is a project co-funded by European Commission within the 7th framework program. In the course of the project (January 2012-December 2013) WalkEGNOS has proposed a website (www.WalkEGNOS.net) to offer different services to people that spend time on the mountains. It is addressed to both leisure and professional users.
The website allows users to share their GNSS generated "walks", but the core and innovative service is the provision of accurate and "EGNOS powered" tracks, that represents an improvement with respect to common GNSS tracks and emerged as a "need" in particular for professional users.
Such service is based on the post processing of the data provided by the users themselves and EGNOS, that, as augmentation service, can supply information useful to improve standard GNSS accuracy and at the same time to provide an estimation of the error done in the computation of the user position.
In order to accomplish a correct position computation the WalkEGNOS post processing engine needs the provision of the so called "raw data" from the user side and the EGNOS corrections available from the EGNOS Data Access Service (EDAS).
A generic user that wants to obtain an "EGNOS powered" record of his/her mountain walk needs a device able to log not only positions but also the raw measurements; such measurements are performed by every GNSS receiver and are used by the receiver itself for the position computation. Once the walk is complete, the user can access the WalkEGNOS website, upload his/her track(s) and obtain the results.
The relevant feature of the website is to be based on the Web 2.0 concept putting users at the centre of the website itself. In order to leverage on this feature, interactions have been also developed with other similar websites and social networks.
The European Geostationary Navigation Overlay Service (EGNOS), improves the open public service offered by the USA's Global Positioning System (GPS).
EGNOS is the precursor to Galileo, the Global Navigation Satellite System (GNSS) currently under development by the European Union. EGNOS and Galileo are part of Europe's GNSS programmes managed by the European Commission.
EGNOS' infrastructure consists of three geostationary satellites over Europe and a network of ground stations. Since it is based on GPS, the EGNOS signal does not require major changes to receivers. Today, many GPS receivers available on the market are also EGNOS enabled.
EGNOS is a satellite-based augmentation system (SBAS) providing both correction and integrity information about the GPS system, delivering opportunities for Europeans to use the more accurate positioning data for improving existing services or developing a wide range of new services.
EGNOS offers three services. These are:
Open Service: The service is provided free of charge without any guarantee or resulting liability. It is open for use to anyone with an EGNOS-enabled satellite navigation receiver.
Safety-of-life Service: EGNOS provides a valuable integrity message warning the user of any malfunction of the GPS signal within six seconds.
Commercial Service: EGNOS provides a terrestrial commercial data service called the EGNOS Data Access Service (EDAS). EDAS disseminates EGNOS data in real time and is the single point of access for the data collected and generated by the EGNOS infrastructure.
As EGNOS provides an unprecedented level of accuracy and reliability, new services can be developed – including for safety-critical applications – in a wide range of market segments (Aviation, Road, Agriculture, Location Based Services and Maritime).
Istituto Superiore Mario Boella (ISMB) is a research & innovation center operating in the Information and Communication Technologies (ICT) domain and working in close cooperation with companies, academia and Public Administration.
ISMB is the coordinator of the WalkEGNOS project and it is in charge of defining the overall system architecture, developing the user devices and coordinating test activities.
ALPHA Consult is a management consultancy that specializes on strategic management consulting services in the space and transportation industries. ALPHA partners with its clients (SMEs, large companies or institutions) to deliver tailor-made solutions that create a lasting competitive advantage.
Within WalkEGNOS project, ALPHA is in charge of defining the user services, developing the project's website and coordinating the dissemination strategy.
Brimatech Services GmbH is a SME specialised in market research and supporting business development activities in technology-intensive markets. Services include the analysis of user needs and requirements, market analysis and analysis of the innovation environment as well as the assessment of innovations from a market- and user perspective. Brimatech´s target groups include national and international research and development consortia, policy decision makers with a focus on technology, research organisations, industry, and start-up companies. In the context of WalkEGNOS Brimatech leads the set-up of a strategic business plan and the commercial feasibility study, including potential ways of integrating with existing GPS-based offerings.
M3 Systems is an SME which provides consulting & engineering services in the space and aeronautics domains to its clients (institutions and private companies). In the field of satellite Radio-Navigation, its expertise is based on innovative receivers architecture and performance evaluations of GNSS Systems (GPS, EGNOS, GIOVE, GALILEO). M3 Systems is in charge of the post processing of raw GPS data sent by users using a EGNOS/EDAS corrections. It measures the “reliability” of the data provided and evaluating tracks quality. The post processing will be performed on a backside server
