WHAT ARE NAVIGATIONAL AID SUBSYSTEM?

Navigational aid subsystem also known as aid to navigation(ATON) are used to assist mariners in determining safe position in relationship to land and hidden dangers. They are placed along water as guides to mark safe water area.

We shall take some of these system one after the other because our aim of doing this is for us to have depth knowledge of it.

The next topic shall be on buoy
