Verbal communication using VHF is used in safety navigation mostly between vessels on the sea. Even though there are communication problems such as language barrier among multinational officers, floods of VHF and noise on dense traffic area, like harbour, no system exists to support that. In addition, as the bridge equipment are controlled independently, it is hard to gather information which is related with navigation and it is difficult to communicate between ships at the same time.
This study is to compensate the defects of VHF verbal communication, and to build user-centered navigation environment up under supporting information confirmation related with navigation and wireless communication. The AIS-ECDIS Related System is designed by improving the problem of former research which is based on ECDIS that can display different information of navigation equipment simultaneously and AIS equipped with function of text communication. The user developed Navigation Support System software interface in order to use AIS text communication easily in ECDIS, and introduced message banner click interface in the NSS software and for more convenience and faster typing.
AIS-ECDIS Related System does not require further installation and can use function of text communication of AIS in ECDIS through user interface of NSS software. As the frequency of the text communication increases, it can ease the floods of VHF communication service in VTS control centers and ports. Moreover, the accuracy of the communication between vessels will be increased by text communication which can prevent collisions caused by intention-awareness failure. Text communication of AIS-ECDIS Related System can be applied in various fields such as ship's arrival and departure report and pilot onboard situation, research data of accident and so on.
Although the AIS-ECDIS Related System still needs to be updated and renewed for its commercialization, but it is worth using as the basic technology of navigation environment of e-navigation navigators centered. The AIS-ECDIS Related System should be developed more and needed additional research for commercialization. However, It is so valuable for navigators to use this as E-navigation as well as assistance system of VHF which collects, analyzes and provides information of vessel equipments.
