Weighting with the pre-knowledge of GNSS signal state of reception in urban areas

Résumé

GNSS accuracy still remains a challenge in dense urban areas where, unfortunately, most of the localization users travel. Propagation effects and, in particular reflections of the signals, induce major inaccuracy measurements of the pseudoranges. For most of the Intelligent Transport Systems (ITS), there is a need to face this source of in accuracy in order to offer new services in a low cost solution. The work presented in this paper has been performed in the context of a French project named CAPLOC that aims to propose accurate localization in dense urban areas in this context .The solutions explored in the projects propose to use only available GNSS signals, and chose some of them or weight some of them in order to increase performances. CAPLOC intends to use the knowledge of the propagation environment close to the antenna to enhance GNSS positioning accuracy.
