- Abstract
Urban environments still form a challenge for Global Navigation Satellite System (GNSS) positioning as they induce difficult conditions for signal propagation. Previous research showed a successful application of the Urban Trench Model to detect non-line-of-sight (NLOS) satellite signals and improve positioning under urban conditions. In this paper, we adapt the approach to the city of Hannover with a detailed 3D city model and focus on the analysis of receiver specific signal characteristics during line-of-sight (LOS) and NLOS phases, herein also investigating the reflection of a signal on building surfaces. The question will be studied whether it is useful to apply a reflection detour on the signal for an improvement in positioning.
