ARCHITECTURE OVERVIEW

PERNASVIP aims to develop a GNSS-EGNOS-based mobility service dedicated to visually disabled pedestrians in urban environment, which meets the 4m level of accuracy and reliability they need for improving their day-to-day life autonomy. The PERNASVIP platform will offer services all along the three travel stages i.e. before (planning), during (visiting destination) and after (remembering and sharing experiences) in order to:

  • Prepare their itinerary at home, taking into account multi-modal public transport routes.
  • Manage their itinerary in real-time, with an accurate positioning.
  • Contact the call centre for any technical or practical request.
  • Share experiences with other users, improve the system and enrich the locations database.

The following figure provides an overview of the architecture of the PERNASVIP system:

The PERNASVIP project primarily intends to retrieve benefits from EGNOS/EDAS data to increase the level of positioning accuracy and reliability as well as the level of service availability. But the PERNASVIP project will also develop a whole set of services aimed to pragmatically support visually impaired people in their day-to-day life mobility:

  • Travelling assistance tools and services covering all journey phases, i.e. journey planning at home, assistance during the trip and addition of comments once back home.
  • Remote assistance services to be in a position to answer any distress call or practical request (problem with the embedded device, itinerary change, question about public transports timetables, etc.).
  • Measurement Quality Check: As part of the algorithm development activities, the PERNASVIP system will aim to provide some form of “quality assurance” indicator which will inform permanently the people about the level of robustness of information delivered by PERNASVIP.

As a result, the PERNASVIP service application will offer the following functionalities:
