Biographie

Originaire de Mézières (Vaud), né en 1964, Pierre-Yves Gilliéron obtient un diplôme dingénieur en génie rural et géomètre à lEcole polytechnique fédérale de Lausanne (EPFL) en 1988.

De 1988 à 1990, il travaille au laboratoire de photogrammétrie de lEPFL où il participe à un projet de recherche en traitement dimage avec le partenaire industriel LEICA.

De 1991 à 1997, il est engagé par un bureau dingénieurs du Valais où il est actif dans le domaine de la géomatique. Responsable du secteur de la photogrammétrie, il dirige des mandats tant en Suisse quà létranger.

En 1997, il rejoint lEPFL et il est nommé chargé de cours pour le positionnement par satellite et la topographie. Parallèlement, Il collabore à la recherche et au développement au sein du laboratoire de Topométrie (TOPO) dans le domaine des systèmes de navigation appliqués aux transports.

Dès 2018, il occupe le poste d'adjoint à la direction de la section en sciences en ingénierie de l'environnement (SIE) de l'EPFL.

Il a été membre du comité de lInstitut Suisse de Navigation (ION-CH), de la commission géodésique suisse (SCNAT/SGK), de commissions d'experts de la VSS, du comité its-ch et de diverses associations professionnelles (IGSO, geosuisse, SSPIT).

SaPPART Guidelines, Performance assessment of positioning terminal

Pierre-Yves Gilliéron

This deliverable, entitled guidelines, is the third outcome of SaPPART COST Action, a European network of scientists and stakeholders that aims to promote smart use of GNSS technology in the field of intelligent road transport and mobility. It discusses the performance assessment of the GNSS-based Positioning terminals (GBPT), which is generally under the responsibility of the system integrators in the road market of GNSS. The aim of this document is to provide guidelines for generic test procedures for the evaluation of GBPT performance, either by field tests, simulations or their combination, compliant with the concepts and the definitions already established in the SaPPART White Paper (TMI 1) and Handbook (TMI 2). The document is intended to provide the reader with a helpful tool for planning the GBPT testing procedures by both discussing the testing in general and by providing some detailed practical information.

Training in Mapping Changes on an Archaeological Site

Pierre-Yves Gilliéron, Bertrand Merminod, Jérôme Zufferey

The evolution of technologies makes surveying accessible to a broader community of professionals and students. Therefore, teaching geomatics is a continuous challenge. This article presents an original pedagogical approach based on a teaching unit gathering students in architecture, as well as in civil and environmental engineering. Working together to collect and visualize data from the built and natural environment is a very stimulating experience. However it requires multiple competences in data analysis and mapping. At the Ecole Polytechnique Fédérale de Lausanne (EPFL), the Faculté de l'Environnement Naturel, Architectural et Construit (ENAC) has introduced a teaching concept called “Projeter ensemble” which consists in a series of multidisciplinary courses. This paper presents a teaching unit for mapping changes of the natural and built environment, focusing on a project carried out in the antique theatre of Aventicum (now Avenches), which is one of the major Roman settlements in Switzerland. The teaching activity has been proposed for 4 years. During this period, restoration works of the antique theatre have taken place and the archaeological site has been surveyed regularly. Hence it is an excellent opportunity to analyse the evolution of the theatre through the comparison of 3D surface models from different epochs. The students benefit from an exciting field of experiment. They collect real data and build 3D models, which they analyse with adequate software. In this sense, they develop very good skills in data processing and in quality assessment of the mapping products. This teaching unit does not aim at training a few specialists in geomatics. However it contributes towards the critical use of modern mapping tools in widespread domains of activities.

Assessment of positioning accuracy of vehicle trajectories for different road applications

Philipp Clausen, Pierre-Yves Gilliéron

Global navigation satellite systems (GNSS) has become a kind of positioning standard due to the high penetration rate of this technology on mass market intelligent transportation systems (ITS) applications. However, this positioning technique remains a real challenge for very demanding ITS services which require continuity and a specific accuracy of the data. This study reports on a practical and methodological approach for the evaluation of the GNSS and multi-sensors positioning and attitude of vehicles in real life conditions. Test scenarios have been set up with several positioning sensors mounted on a vehicle for the collection of raw data on different road sections. The measurement of a high quality reference trajectory with an accuracy of several centimetres allows to estimate position accuracy under different environmental conditions. The authors will show in detail the results and identify some typical situations (e.g. sub-urban environment) where the quality of positioning parameters is reduced to several metres instead of dm and may impact the level of ITS services, e.g. road user charging or safety applications. This study results from the methodology developed in the satellite positioning performance assessment for road applications COST Action on the performance assessment of positioning terminals for ITS.
