Abstract

Reliable, available and accurate localization of people and vehicles is one crucial requirement for intelligent transportation systems (ITSs). This has led to a variety of technical approaches in recent years. Towards an exact positioning via Global Navigation Satellite Systems (GNSSs) the visibility of satellites is an important factor. In this paper, we review the literature regarding the positioning under non-line-of-sight conditions and analyze a range of topics from explicit modeling to empirical data collection. The variety of research indicates a growing interest in robust localization in urban areas. Furthermore, we develop a taxonomy of the technical design for GNSS applications dealing with non-line-of-sight and a typology of the measuring instruments. Both is based on an extensive analysis and review of the state-of-the-art. In doing so, we characterize the current research road map. Thus, the goal of this work is to provide a starting point in terms of the state-of-the-art for further research activities in robust GNSS positioning and the opportunity for technological innovations to ITS.
