Real-time atmospheric modelling for centimetre-level positioning based on Global Navigation Satellite System (GNSS) continuously operating reference station networks

This contribution describes a recent Australian Research Council (ARC) project funded under the ARCLinkage Scheme. The research team comprises researchers from RMIT University, UNSW, University of Melbourne, Spatial Information Infrastructure and the Department of Lands, NSW. The aim of the project is to enhance the utility of continuously operating reference station (CORS) networks in the states of Victoria and New South Wales by developing improved atmospheric correction models to support high accuracy, real-time positioning even when the density of reference stations is insufficient for standard operational GPS techniques such as RTK ('real-time kinematic')
