5.24.1 COLLISION AVOIDANCE

Problems of Collision Avoidance in Navigation
Marine collision avoidance is one of the problems that have been recognized from of old. Now, it will be
described briefly who the collision avoidance is positioned among the navigational aid problems.
The navigation pattern of all mobile craft constitutes a system with some closed loops regardless of the
media through which the mobile craft travels, whether air, water, the boundary between air and water, or
space. This pattern consists of two closed loops in principle, one of which is a collision with another
mobile craft and the other is a loop of finding a right and safe way to reach a predeterminate destination.
Fig. 5-24-1 shows the conceptual diagram of navigation pattern by MR. E.W. Anderson. The closed loop
of collision avoidance is shown on the left side and the closed loop of finding a right course on the right
side.
