Abstract

REE N°5/2018 Z107 JOURNEES SCIENTIFIQUES URSI 2018 DOSSIER 2 In the past decades, more and more Global Navigation Satellite Systems (GNSS)- based urban transport applications emerged. Among these applications, the lia- bility critical ones, such as Electronic Toll Collection (ETC) and Pay as you Drive insurance, have high requirements for positioning accuracy as well as integrity since large errors can lead to serious consequences. Yet urban environments present great challenges for GNSS positioning due to the existence of multipath effects and None-Line-of-Sight (NLOS) receptions. This article presents a com- plete integrity monitoring scheme for urban transport applications. This scheme is realized in several levels. Firstly, measurement errors are better characte- rized by using weighting models with the help of an Urban Multipath Mode- ling (UMM). Secondly, several Fault Detection and Exclusion (FDE) methods are applied in order to detect and exclude erroneous measurements. Finally, Hori- zontal Protection Levels (HPLs) are computed and the probability of Misleading Information (MI) is analyzed. Au cours des dernieres decennies, de plus en plus d’applications de transpor
