WalkEGNOS investigates the possibility to generate a data base of accurate and reliable GNSS tracks, collected on field with low cost devices and augmented off line with EGNOS and EDAS data.

Istituto Superiore Mario Boella (Italy): no profit research centre in the field of ICT. Coordinator, role in the system definition, prototypes development and tests

Brimatech Services GmbH (Austria): market research and consulting. Role in market analysis, commercial feasibility and business plan

Alpha Consult s.r.l (Italy): strategic consulting in GNSS. Role in requirements management, creation of web site and WalkEGNOS community M3 Systems (France): independent SME, specialized in space, ATM and transport applications. Role in system design and EGNOS augmentation engine

3Motivation and Current Limits24/04/2013European Navigation Conference 2013 April 23-25, Vienna 4Problems addressed by WalkEGNOS:

Available maps are often not up to date and/or inaccurate;Mapping on a voluntary basis in not validated;Professional mapping is expensive

424/04/2013European Navigation Conference 2013 April 23-25, Vienna 5Expected Major OutcomesThe database containing information on reliable routes will:

open new opportunities for high quality leisure/touristic services

be of great value for search and rescue operations(needs confirmed during the interviews with stakeholders in the first part of the project)

useful for Organisations entrusted with the maintenance of paths

The availability of WalkEGNOS augmented tracks can represents an important added value for different field of applications: It can create new opportunities for leisure and touristic servicesSearch and Rescue operations, as confirmed during interview to the stakeholdersFurthermore, such tracks can be very useful for organization devoted to the maintenance of the paths

ServicesThis is a general overview of the system architecture, that shows at the same time the main use cases. WalkEGNOS concept foresees that volunteers will carry on a portable terminal able to record RINEX within SD card collected the path, called custom device. At the end of the path, the volunteers will upload raw data to the web site (the core of the architecture). PPE is in charge to post process RINEX with EGNOS\EDAS information in order to provide accurate tracks assessed with Protection Level. Output tracks, stored by website, can be downloaded by users and can be exploited by means of commercial personal devices (e.g. Smartphones, GNSS personal handset).The system was studied in order to guarantee the interoperability with external web portal and interaction with social networks. It has to be remarked that each component can be exploited for other purposes.6WalkEGNOS WebSite24/04/2013European Navigation Conference 2013 April 23-25, Vienna 7USERSEGNOS/ ESA-FTP WalkEGNOS EngineData uploadPersonal informationPersonal data storage Tracks uploadedPoweredTracksPowered Tracks Storage (displayed on a map)Powered Tracks download

It is the access point toward the service for the users, that will have personal page from which it would be possible to upload raw data, download powered tracks and provide additional information. Website backend provides acces to the Post Processing engine for the tracks computation and permits the access to the service to external web portal, both for post processing request and for track download.7
