Hi, I am Zhengdao Li, a second-year Ph.D. student in the Intelligent Positioning and Navigation Laboratory at The Hong Kong Polytechnic University, under the supervision of Prof. Li-Ta Hsu.
My current research interests include non-Gaussian GNSS error modelling, robust statistical methods for urban positioning, and integrity monitoring for safety-critical navigation applications.
