PolyU Aviation Researcher Supported by Google to Advance Urban Positioning and Navigation Technologies

Urban navigation has undergone substantial technological advancements in recent decades, enhancing smart living environments while improving human life. With his ongoing research in this impactful field covering location-based services and navigation and positioning technologies, Dr HSU Li-Ta, Associate Head and Associate Professor of the Department of Aeronautical and Aviation Engineering, and Limin Young Scholar in Aerospace Navigation of The Hong Kong Polytechnic University (PolyU) has received an unrestricted grant from Google to advance research in Global Navigation Satellite Systems (GNSS) and sensor fusion technologies. Titled “Research on 3D Mapping Aided GNSS Precise Positioning for Vehicular Applications,” Dr Hsu's awarded project centers on a novel urban positioning and navigation method to be used in mobile phones and intelligent vehicles. In densely built-up urban areas with skyscrapers like Hong Kong, GNSS positioning may be inaccurate as satellite signals are reflected off buildings. The new method utilizes 3D mapping technology to calculate the length and strength of the reflection of signals, thereby achieving a remarkable lane-level positioning accuracy in urban areas.  Dr Hsu has previously worked with Google’s Android Location Team in Mountain View, California as a visiting research scientist. During his visiting, he collaborated closely with industry leaders to enhance mobile positioning technologies by improving the accuracy and reliability of GNSS and sensor fusion. The outcome of his research has been applied to location services on Android devices, benefitting a large number of phone users worldwide. The grant aims to encourage leading researchers in advancing technology with innovation. It willprovide support for Dr Hsu’s pioneering work into GNSS and sensor fusion technologies, addressing the evolving demands for precise and trustworthy positioning technology for better user experiences, and exploring new opportunities for urban applications. Dr Hsu said, “It is a profound honour to receivethis grant. I am grateful for the invaluable experience and support provided by my colleagues at PolyU and collaborators at Google. Working with the experiences I obtained in Android Location Team, in particular, presented me with a unique opportunity to push the boundaries of mobile positioning technology. With the support of this grant, I hope to explore new solutions that can make GNSS technology more robust and accessible for users worldwide.” Dr Hsu was a two-time winner of the PolyU President’s Awards for Outstanding Achievement, in the category of Knowledge Transfer in 2021 and of Teaching in 2023 respectively. The grant further highlights his outstanding research as well as PolyU’s contribution to global urban navigation and mobile positioning technologies.   Reposted from Research and Innovation Office, The Hong Kong Polytechnic University [Original post]
