Welcome to the ICL-GNSS event homesite! ICL-GNSS is an annual conference, held, for its 3rd edition, in Turin, Italy, from the 25 to the 27 of June 2013. The conference is focused on localization and Global Navigation Satellite Systems. It provides a high-quality publishing forum with peer review, and emphasizes at the same time quick turn-around time. Driven by both market trends and legal regulations, there is a high demand for providing a robust localization solution, which will be available continuously, regardless the specific environment, i.e., outdoors and indoors, and on different platforms such as stand-alone navigators, PDAs and mobile devices. ICL-GNSS thus addresses both satellite-based and complementary technologies. The event is based on contributed peer-reviewed papers and will include world-class invited keynote presentations.
