About Me

Dr. Weisong Wen is a Research Assistant Professor at the the Department of Aeronautical and Aviation Engineering, The Hong Kong Polytechnic University. He was the Associate Director of Intelligent Positioning and Navigation Lab-IPNL which is led by Dr. Li-ta Hsu (He is also my Lifelong Mentor). This page is part of the IPNL and provide the latest update of the regular news.

Dr. Wen received a BEng degree in Mechanical Engineering from Beijing Information Science and Technology University (BISTU), Beijing, China, in 2015, and an MEng degree in Mechanical Engineering from the China Agricultural University, in 2017. After that, he received a PhD degree in Mechanical Engineering from The Hong Kong Polytechnic University (PolyU) supervised by Dr. Li-ta Hsu, in 2020. He was also a visiting PhD student with the Faculty of Engineering, University of California, Berkeley (UC Berkeley) in 2018, supervised by Dr. Zhan and Prof. Tomizuka. Before joining PolyU as a Research Assistant Professor, he was a senior research fellow at AAE of PolyU. He has published 24 SCI papers and 20 conference papers in the field of GNSS (ION GNSS+) and navigation for Robotic systems (IEEE ICRA, IEEE ITSC), such as autonomous driving vehicles. He won the Innovation Award from TechConnect 2021, the Best Presentation Award from the Institute of Navigation (ION) in 2020, and the First Prize in Hong Kong Section in Qianhai-Guangdong-Macao Youth Innovation and Entrepreneurship Competition in 2019 based on his research achievements in 3D LiDAR aided GNSS positioning for robotics navigation in urban canyons. The developed 3D LiDAR-aided GNSS positioning method has been reported by top magazines such as Inside GNSS and has attracted industry recognition with remarkable knowledge transfer. His mission and dedication are to investigate reliable methods to improve the GNSS positioning in urban canyons, which is of great importance for reliable robotic navigation.
