A formal description of navigational process

In this paper there is undertaken an attempt to present the formal description of the ship’s navigation process. This formal description takes into account not only all the most important ship’s characteristics that influence the ship’s motion but also all the most important environmental characteristics influencing the ship’s behaviour at sea. The formal description comprises the following issues: ship’s navigation process, navigational information, dynamic of the ship’s motion, equations describing the ship’s navigation process, and mathematical models of ship’s navigation process.
