Résumé

Global Navigation Satellite Systems (GNSS), such as GPS, are more and more playing a key role in the development of new traffic applications and services, such as those making use of “Geofencing” techniques, electronic tolling systems being the most famous among them. Geofencing needs geopositioning and, in most of the case, geopositioning with a certain level of quality, in particular in terms of integrity for the liability-critical applications. The EGNOS system is the European Wide Area Augmentation System for GPS and has been built, upon air transport specifications, to increase the accuracy, but mainly the integrity of GPS system. The French Ministry in charge of Transport, the MEEDDM, has funded a specific study, called “EGNOS-On-The-Road”, to assess, thanks to full-scale experiments in real-life conditions, the improvements that can be expected from EGNOS for road applications, compared to GPS. The authors first describe the experimental test bench, the GNSS sensors and the data processing that have been used. Then they present the results, in terms of availability, accuracy, integrity an in terms of adequacy to the application needs, for several types of sensors: stand-alone GPS receivers or EGNOS/GPS receivers, used with internal and external antennas. The paper ends with a conclusion and high-level recommendations.
