Baseband Signal-level GNSS Accuracy and Security Reinforcement
Global navigation satellite system (GNSS) plays an irreplaceable role in many areas such as unmanned autonomous systems. In this talk, the evolution of GNSS receiver architectures and the associated baseband signal processing algorithms will be discussed. In specific, the speaker will present his recent research works on vector tracking loop (VTL) and direct position estimation (DPE).
The talk will show the superiorities of VTL and DPE in GNSS-challenging environments e.g. multipath and non-line-of-sight (NLOS) receptions. On the other hand, the speaker will also present his research on an evolving and emerging topic, i.e., GNSS spoofing. Both postprocessing and real-time modes of spoofing generation are proposed. A baseband signal-level spoofing detection algorithm will also be introduced in the talk.
Dr. Bing XU received his Bachelor's degree in Network Engineering from Nanjing University of Science and Technology, China in 2012. He was awarded his Ph.D. degree in Control Science and Engineering from the same university in 2018. Prior to his current position as a Research Assistant Professor with the Department of Aeronautical and Aviation Engineering (AAE), The Hong Kong Polytechnic University, he was a Postdoctoral Fellow with AAE from August 2018 to April 2020.
His research interests include signal and system theory, satellite navigation and positioning, GNSS receiver design, GNSS security reinforcement, cellular/low earth orbit satellite positioning, etc. Dr. Xu has been awarded several research grants including NSFC for Young Scientists, Guangdong Natural Science Foundation, RGC Research Impact Fund Scheme (as Co-PI), as well as Huawei research collaborative project. He has published more than 25 papers in peer-reviewed journals.
