WalkEGNOS Consortium 24/04/2013European Navigation Conference
2013 April 23-25, Vienna3 WalkEGNOS is a two years (2012-2013)
collaborative European project funded by the European Union's
Seventh Framework Programme (FP7/2007-2013) under grant agreement n
277656-2. 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):

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
Slide 5
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
Slide 13
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

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
