The use of navigation AIDS for ships to provide certain convenient conditions for navigation in the course of navigation in the sea or inland rivers: to enable them to see the navigation conditions and understand the potential dangers that may be encountered during navigation in harsh environments such as night and foggy days. This will help reduce or eliminate safety hazards in advance.">The use of navigation AIDS for ships to provide certain convenient conditions for navigation in the course of navigation in the sea or inland rivers: to enable them to see the navigation conditions and understand the potential dangers that may be encountered during navigation in harsh environments such as night and foggy days.
