Abstract:	In the course of the past year or so, several papers have been presented here and abroad dealing with the utilization of transponders in ship’s navigation. Multiple usage transponder systems are available as aids for both navigation and target recognition by Radar. Extensive research for additional uses of transponders is continuing on a broad scale in the United States (to mention the largest-All Weather RIHANS through a USCG contract to RCA) and similarly in Great Britain and Holland (Small Platform Recognition by TN0 of The Hague). Sperry research is aimed at incorporating transponder systems into the Radar display to achieve Own Ship/Target identification and selective com- munication. All this sophisticated instrumentation development is directed toward the future when centralized automation will facilitate the implementation and servicing of the equipment. What we really need now is a short cut to eradicate the ambiguity of the Radar computed Predicted Situation. In spite of the upgraded sophistication and reliability of today’s Radar and the great emphasis on personnel training, the primary inherent shortcoming of the Radar system, namely, unambiguous prediction of the future situation based on the utilization of the latest known information, is still with us. A simple system is needed which can operate on present day ships, now-today-with today’s personnel. This system must be commercially feasible, in cost and maintenance, and, be compatible with presently used instrumentation on board the average ship. The year by year rising losses in life and ships caused by collisions demand it. One proposed system is presented here.
