Abstract: Based on function requirement analysis, an intelligent navigation system particularly for cargo ships sailing in the Suez Canal is developed. The virtual test platform that simulates a ship in operation is used to verify functions of the navigation system. An Intelligent navigation system consists of a variety of modules, such as perception, decision-making, control, actuator, feedback, etc. The virtual test platform provides necessary environment for testing all the modules and the complete system and plays an indispensable role.
