The speaker during the banquet dinner was Professor Li-Ta Hsu, Hong Kong Polytechnic University and currently on a one-year sabbatical at Google,

Profesor Hsu spoke on the topic: Navigating accurately in cities: Vision-sensor-aided GNSS real time kinematic. 

Professor Hsu Biography:   
Li-Ta Hsu received B.S. and Ph.D. degrees from National Cheng Kung University (NCKU), Taiwan, in 2007 and 2013, respectively. He is an Associate Professor and Associate Head in the Department of Aeronautical and Aviation Engineering (AAE) at The Hong Kong Polytechnic University (PolyU), Hong Kong. He is currently at Google on sabbatical. Professor Hsu is an ION Per Enge Early Achievement Award recipient. His research interests are urban GNSS positioning, indoor positioning, and multi-sensor integrated navigation systems for autonomous systems.
