An HW-In-the-Loop Approach for the Assessment of GNSS Local Channel Effects in the Railway Environment

Abstract

is a Communication engineer, currently employed at the Navigation Technologies research area of the Istituto Superiore Mario Boella (ISMB), in Turin, Italy. He received a M.S. in Communications Engineering in 2007 from Politecnico di Torino, Italy. Since 2011, he holds a Ph.D. degree in Electronic and Communication. His interest focuses on multi-sensors fusion, particularly between GPS and inertial navigation systems, as well as on advanced processing techniques for dual frequency and multi-constellation GNSS receivers. Mario Nicola received the M.S. in Computer Science Engineering from the Politecnico di Torino in 2002. In 2005 he obtained his Ph.D. degree in Electronics and Communications Engineering working on reconfigurable architectures for wireless communication systems. He is a researcher in the staff of the Navigation Technologies research area at ISMB, Torino. His main activity is the implementation of algorithms for software radio GPS/Galileo receivers. Emanuela Falletti is the head of the GNSS Core Algorithms unit in the Navigation Technologies research area of the Istituto Superiore Mario Boella (Torino, Italy). She received her M.S. degree in telecommunications engineering in 1999 and her Ph.D. degree in electrical and communications engineering in 2004, both from the Politecnico di Torino, Italy. Her research activity focuses on digital signal processing techniques and algorithms for advanced GNSS software receivers, including interference detection and mitigation, multi-antenna processing, as well as signal simulation.

BDS B1I multipath channel statistical model comparison between static and dynamic scenarios in dense urban canyon environment

“…The multipath characteristics, such as the delay spread, power attenuation, lifespan, and Doppler frequency, were reported and compared for urban and suburban environments and for land mobile and pedestrian platforms Lehner 2004, 2008;Lehner and Steingass, 2005;Steingass et al 2017). Falco et al (2018) implemented this model by a hardwarein-the-loop approach to evaluate the multipath effects in railway environments. However, the consistency of these characteristics with the real GNSS multipath channel still needs to be validated.…”
