WalkEGNOS Consortium 24/04/2013European Navigation Conference 2013 – April 23-25, Vienna3 WalkEGNOS is a two years ( ) collaborative European project funded by the European Union's Seventh Framework Programme (FP7/ ) under grant agreement n° 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

Motivation and Current Limits 24/04/2013European Navigation Conference 2013 – April 23-25, Vienna4 Problems addressed by WalkEGNOS: 1.Available maps are often not up to date and/or inaccurate; 2.Mapping on a voluntary basis in not validated; 3.Professional mapping is expensive

24/04/2013European Navigation Conference 2013 – April 23-25, Vienna5 Expected Major Outcomes The 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

Post Processing Engine 24/04/2013European Navigation Conference 2013 – April 23-25, Vienna12 Independent remote unit able to post process RINEX files and provide in output EGNOS powered tracks; Tracks will be more accurate respect to standalone GPS receivers; Tracks will be provided with associated quality index based on computed Protection Levels (PLs) PLs are used by the PPE to select the best track, when comparing 2 different tracks related to the same path

Custom Device 24/04/2013European Navigation Conference 2013 – April 23-25, Vienna13 WalkEGNOS relies on the post processing of raw GNSS observables (i.e.: pseudoranges), that are not provided by portable commercial devices equipped with GNSS receivers (e.g. smartphones, personal navigator); The project includes the development of prototypal device to demonstrate advantages offered by EGNOS/EDAS; Wearable, embedding a commercial GNSS module, able to store RINEX files required for post processing; Open platform (the software package is based on Microsoft.NET Micro Framework) connected to communities of developers; Matches user requirements identified in the first phase of the project: Portability Low cost Easiness of use Battery lifetime SD card interface

Data Collection 24/04/2013European Navigation Conference 2013 – April 23-25, Vienna14 Data collection was performed in a real mountain environment 1.a path in a clearing on the valley side with good sky visibility, canopy coverage almost absent. 2.a path in a wood on the mountainside with fair sky visibility and medium canopy coverage Reference path surveyed with geodetic GPS receiver (dual freq, DGPS, RTK) OPEN WOOD

Conclusions WalkEGNOS project creates a flexible web 2.0 platform for mapping service to enhance the quality of tracks currently available; The system improves track accuracy, post processing GNSS raw measurements collected with low cost terminals (Custom Devices), and enhance the results with EGNOS\EDAS information; WalkEGNOS investigates the use of the EGNOS Protection Levels applied in pedestrian navigation; Preliminary tests confirm promising results with enhanced accuracy and tracks reliability; WalkEGNOS outputs can be addressed to different fields of application, such as leisure (e.g. hikers) or professional (e.g. SAR) uses. Furthermore, WalkEGNOS architecture foresees the integration with third party technologies. 24/04/2013European Navigation Conference 2013 – April 23-25, Vienna19
