One of the basic problems in marine navigation is to ensure the safe conduct or a ship. Striving to raise the level of navigational safety, improvement in efficiency and competitiveness of sea transport, have given rise to the idea of working out an active vesseI traffic supervision system. The activeness of the system consists in active exchange of information between vessels and the shore centre. The system will enable the watch officer to make the optimal decisions and thereby raise safety of navigation by providing him with suitably selected ordered navigational information on an ergonomic operator's indicator. The methods of vessel traffic control applied so far are based on shore radar stations tracking the units sailing in appointed supervision zones. The basic problem in these systems is relatively low accuracy and considerable inertia in tracking the objects, maneuvering objects in particular. This results from the nature of radar observations and the applied methods of state estimation of tracked objects. Another problem is the one-sidedness of information in the possession of only the shore observation centre, which, to be true, can observe the movement of units in the supervision area, but can impart information only verbally. A new approach in the construction of traffic supervision systems is the concept of a bilateral interactive automatic exchange of navigational information between sailing units and the shore centre. In the active VTS system every ship transmits to the shore centre the information it possesses, mainly about its own position, course and speed as also about the objects watched by it, and receives in return suitably selected and relevant-to-itself information about other objects in the area. Thanks to an approach like this the watch officer will have precise information about potentially threatening collisions with other vessels even when he will not be able to track them with his own technical means. The basic merit of the system suggested is making use of precise navigational information presented on a spatial numerical navigational chart. A three-dimensional presentation of bathymetric information, combined with visualization of objects tracked, will make it possible to navigate accurately and safely in sea and inland waters, even in navigationally difficult regions, regions with high intensity traffic included.The paper develops the concept of a future interactive system of vessel supervision and control.
