To advance and push the development of GNSS applications, which currently still suffer seriously from multipath reception, areas of work at DLR cover all relevant issues related to multipath, reaching from the aforementioned measurement campaigns and the development of high-realistic channel models to subsequent hardware/software simulation of navigation receivers and the development and assessment of novel mitigation algorithms. After an introduction to the aeronautical and urban GNSS channel models developed by DLR, a newly developed time-domain sample-true GNSS simulation software is introduced. In the subsequent paragraph novel particle-filter based algorithms for multipath mitigation are described. Combining these three components (GNSS channel models - realistic GNSS simulation - particle-filter multipath mitigation) culminates in the assessment of multipath errors in safety-critical applications such as aviation, and the simulation-based verification of novel receiver signal processing methods as well as the assessment of navigation signals under realistic propagation conditions.
