The application of virtual aids to navigation(V-AtoN) is of great significance in excavating navigation depth,reducing maintenance costs,and improving navigation assistance efficiency.To solve the problems existing in the application of V-AtoN on the Yangtze River,a preliminary application model for V-AtoN is established.Three types of application scenarios for V-AtoN enhancement,substitution,and addition are proposed.The display method of combining circular and entity AtoN symbols,solid and dashed line distinguishing synthesis from virtual,and text distinguishing publishing carriers are defined.A publishing method that the permanent V-AtoN issued by AIS should be published on the electronic navigational charts is proposed.Thus,the application mode of V-AtoN on the main line of the Yangtze River is initially established,and demonstration applications have been carried out based on digital waterways and electronic navigational charts.The research result can provide reference for the standardized application of V-AtoN on inland rivers.
