Abstract

Satellite positioning accuracy is degraded by multipath propagation between satellite and the receiver. In this paper we give an overview of a new approach to model and correct this impairment, and present some preliminary results. High accuracy 3D laser scanning is utilized to model the environment. This gives an accurate basis for the characterization of the satellite to earth radio channel by using ray tracing. The information extracted from the ray tracing simulations is used to design correction algorithms that will be implemented in GNSS software defined radio (SDR) receivers.
