LSGI PhD Student Won a Young Author Best Paper Award at the World’s Largest GNSS Conference

PhD graduate Yangzhao Gong from the Department of Land Surveying and Geo-Informatics (LSGI), Faculty of Construction and Environment, The Hong Kong Polytechnic University (PolyU), recently received a Young Author Best Paper Award (the third order) at the 12th China Satellite Navigation Conference (CSNC), Nanchang, China, 26 to 28 May 2021. The awarded paper was entitled “Augmenting GNSS PPP Accuracy in South China Using Water Vapor Correction Data from WRF Assimilation Results,” in which atmospheric water vapor data were remotely sensed by a network of GNSS ground receivers and then assimilated into the Weather Research and Forecasting model (a widely used Numerical Weather Prediction model). The water vapor data forecast by the WRF model were then utilized to correct the atmospheric errors in GNSS observations. The test results in the South China region showed that the accuracy of GNSS positioning and navigation solution can be significantly improved by 25% to 35% in static mode and 15% to 26% in kinematic mode.

Media interview for harnessing technology to monitor tree stability

Dr Charles Wong, Associate Professor of LSGI, and his research team were interviewed by TVB for his project on Smart Monitoring System for Urban Tree Management in May 2021. The interview was showed on news 創科館 and programme 創科導航. The project was also covered in TVB programme 武測天.

LSGI scholar provides Mars landing site mapping and evaluation

Two research teams at The Hong Kong Polytechnic University (PolyU) contributed to the Nation’s first Mars exploration project Tianwen-1. By harnessing their extensive experience in the field of aerospace science and technology, as well as their commitment to research excellence, PolyU researchers played a vital role in the Tianwen-1 mission, in collaboration with the China Academy of Space Technology (CAST). Professor WU Bo helped identify possible landing regions with advanced topographic mapping and geomorphological analysis technologies. Professor YUNG Kai-leung developed a sophisticated space instrument, the “Mars Landing Surveillance Camera (Mars Camera)”, for capturing images of the surroundings of the Red Planet and monitoring the status of the Zhurong Mars rover. 

Press sharing on LSGI smart cities related research

On 26 April, a press conference was conducted at PolyU by Prof. John Shi, Chair Professor of LSGI and Director of Smart Cities Research Institute to share a number of cutting-edge patented technologies and research by his research group. These projects help address various societal issues, including the revitalisation of old buildings, slope safety, prevention and control of the COVID19 pandemic, and the construction of spatial data infrastructure, hoping to provide comprehensive solutions for smart city development in Hong Kong and the Nation.
