Accurate Localisation Based on GNSS and Propagation Knowledge for Safe Applications in Guided Transport

AbstractGlobal Navigation Satellite Systems (GNSS) are widely spread (with Global Positioning System - GPS) in intelligent transport systems and offer a low cost, continuous and global solution for positioning. Unfortunately, urban users are often the most demanding of accurate localisation but receive a degraded service because of signal propagation conditions. Several mitigation solutions can be developed. We propose, within the CAPLOC project (2010-2013) to deal with inaccuracy by associating image processing techniques for a 3D reconstruction of the surrounding environment and the signal propagation knowledge
