Development and Simulation of Virtual Navigation Mark System

The implement method of virtual navigation mark system is discussed and its application software based on VB and MapX is developed.This virtual navigation mark system is simulated by using AIS equipment.The relationship between ship and navigation marks can be visually monitored in electronic chart display terminal,and the distance between vessel and virtual navigation marks in sailing process can be judged with the help of electronic chart space analysis function.The simulation results have proved the feasibility of realizing the virtual navigation mark technology adopted in the paper and also provides a theoretical foundation to evaluate real ship virtual navigation mark system.
