A STUDY ON THE NAVIGATION DECISION SUPPORT DISPLAY SYSTEM - A STUDY ON A VOICE ALARM INDICATION OF ARPA

In the conventional ARPA (Automatic Radar Plotting Aid) system, several kinds of alarm are generated, which are identified by different buzzer tones or symbols and characters displayed on a CRT. A situation can occur, where there is not enough time for navigators on the bridge to confirm the meaning of alarms, especially in congested navigable waters. This means that the effective use of information is difficult in a conventional ARPA system and this leads to a delay in collision avoidance action. The usage of ARPA was investigated under actual ship operation. It was found that the frequency of alarm generation is high, especially in mistaking targets. Also, the fact that conversions concerning the lookout are patterned, information concerning the movement of other ships is suitable for language processing by computer. On the basis of those results, a new system of Voice Alarm Indication of ARPA is proposed. In this system, data from ARPA is processed and the aural information regarding the movement of other ships including targets mistaken is indicated in accordance with certain decisions.
