For safety-critical applications such as air navigation, unmanned systems, etc., GNSS positioning, navigation, and timing (PNT) accuracy and security are highly demanded. In this talk, we will dive into GNSS receivers to make use of deeper-level measurements so as to find solutions for enhanced PNT accuracy and security. Dr Xu will introduce and show the superiority of advanced receiver architectures such as vector tracking loops, direct position estimation, and machine learning assisted GNSS signal processing. On the other hand, Dr Xu will also present the research on the evolving and emerging topic, i.e., GNSS spoofing. Both post-processing and real-time modes of spoofing generations are proposed. An image-based post-correlation way for continuous spoofing detection will also be introduced in this seminar. 


Dr Bing Xu received his BEng degree from Nanjing University of Science and Technology, China in 2012. He was awarded a PhD degree in Control Science and Engineering by the same university in 2018. He was a Postdoctoral Fellow with the Department of Aeronautical and Aviation Engineering, The Hong Kong Polytechnic University (PolyU AAE) from Aug 2018 to Apr 2020. Since Apr 2020, he has been a Research Assistant Professor with PolyU AAE. His research focuses on signal and system theory with applications to satellite navigation and communication. Dr Xu has been leading research projects including NSFC for Young Scientists, Guangdong Basic and Applied Basic Research Fund, Huawei research collaborative project, RGC Research Impact Fund (as Co-Principal Investigator), etc. He has published more than 25 papers in peer-reviewed journals. He has been teaching control-related courses.
