Approach Parameters in Marine Navigation – Graphical Interpretations

Abstract

In this paper approach parameters widely used collision avoidance systems such as the distance at closest point of approach and time to the closest point of approach and less known and used as the distance on course, the distance abeam and any distance and the times intervals to their occurrences are derived, analyzed and graphically interpreted in the combined coordinate system for position and motion. They can be used in collision avoidance systems and for reversed purposes - manoeuvring to required approach parameters, intentional approaches and naval tactical manoeuvres.
