Bio

Fran Fabra received both the M.Sc. degree in telecommunication engineering and the Master degree in Information and Communication Technologies from Universitat Politècnica de Catalunya (UPC), in 2007, and the Ph.D. degree from the Universitat Politècnica de Catalunya, Barcelona, Spain, in 2013. He developed his Master’s thesis on security in aeronautical mobile networks at TriaGnoSys GmbH, Munich, Germany. His Ph.D. dissertation was dedicated to research of the GNSS-⁠R concept towards remote sensing of the cryosphere.

From December 2007 to December 2019 he was with the Earth Observation Research Group from the Institute of Space Sciences (ICE-⁠CSIC/⁠IEEC), Barcelona, Spain, working on applications of global navigation satellite systems for remote sensing of the Earth. Such experience ranged from the theoretical study of pioneering GNSS-R techniques, until their experimental proof of concept and validation from real data analysis. He was also the main developer of the open source wavpy library for GNSS-⁠R analysis and modeling.

In November 2019, he joined as a Postdoctoral researcher the Signal Processing for Communications & Navigation Group, Universitat Autònoma de Barcelona (UAB/IEEC), Spain, where he became an Associate Professor in May 2024.

Research interests

His research interests lie in the field of statistical GNSS signal processing and antenna array analysis.
