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.
