Colloquium Speaker: Professor Pau Closas presents a talk on "Secure Satellite-Based Navigation Systems"

Global Navigation Satellite Systems (GNSS) is the technology of choice for most position-related applications, when it is available. A GNSS receiver relies on a constellation of satellites to estimate a set of range measures from which to compute its position. These distances are calculated estimating the propagation time that transmitted signals take from each satellite to the receiver. The term GNSS encompasses GPS, Galileo, GLONASS, or Beidou systems among others. The main challenges of GNSS technology arise when operating in complex environments which are either naturally impaired by multipath, shadowing, high dynamics, or ionospheric scintillation; or intentionally/unintentionally interfered. In the last decade, ushered by an ever increasing demand for availability, accuracy, and reliability, the mitigation of these challenges has steered intense research on advanced receiver design. The main goal of this talk is to introduce the GNSS landscape and, motivated by its widespread use, highlight the need for securing and protecting GNSS infrastructure. The main threats and sources of interferences are classified, along with their impact and potential mitigation strategies that one might adopt at the receiver side.


Pau Closas received the MS and PhD in Electrical Engineering from the Universitat Politècnica de Catalunya (UPC) in 2003 and 2009, respectively. He also holds a MS degree in Advanced Mathematics and Mathematical Engineering from UPC since 2014. In 2003, he joined the Department of Signal Theory and Communications, UPC, as a Research Assistant. In 2008 he was Research Visitor at the Stony Brook University (SBU), NY, USA. In 2009 he joined the CTTC, where he was Senior Researcher and Head of the Statistical Inference for Communications and Positioning Department. His primary areas of interest include statistical and array signal processing, estimation and detection theory, stochastic filtering, robust statistics, and game theory, with applications to positioning systems, wireless communications, and mathematical biology.

He is the recipient of the EURASIP Best PhD Thesis Award 2014, the 9th Duran Farell Award for Technology Research, and the 2016 ION’s Early Achievement Award, in recognition to his contributions to navigation systems and signal processing fields. He served in the organization committees of flagship conferences, for instance, as Publications Chair of the IEEE SSP 2016 and the IEEE ICASSP 2020 conferences. He is also Guest Editor of special issues in the IEEE Trans. on Vehicular Technologies, the Proceedings of the IEEE, and the IEEE Sig. Proc. Magazine.
