Résumé / Abstract
One of the main drawbacks of GNSS (Global Navigation Satellite Systems) in urban environments is the fact that signals may arrive at the receiver antenna only in Non-Line-Of-Sight (NLOS) conditions, leading to biased pseudorange estimates when they are taken for granted by the receiver and eventually wrong positioning. This article presents a study on the benefits of using 3D maps of cities to decide whether or not the GNSS signal coming from each tracked satellite is reliable. For that, two different 3D maps and two methodologies are presented and compared. The results show the interest of this approach.
