Domestic shipbuilding industries have the greatest amount of orders and the best outputs in the world. Also, the level of domestic technology related to shipbuilding is 85%. Compared with advanced countries, navigation, the field of communicating instruments, and technology of the equipment for highly value added ships are insufficient.
As a result of this, korean government are making domestic researches of highly value added products of the field of oceanic industries such as automatic navigation devices, navigating equipments, and etc. active. Up-to-date navigating devices include AIS(Automatic Identification System), VDR(Voyage Data Recoder), ECDIS(Electronic Chart Display and Information System), Sound Reception System, EPA(Electronic Plotting Aid), and ATA(Automatic Tracking Aid).
As a fundamental stage to develop ECDIS(Electronic Chart Display and Information System), this research has realized that a function of basic navigation, a function of EBL(Electronic Bearing Line) of a radar, a function of VRM(Variable Range Marker), a function for referring objects, and a function for displaying radar targets have been supplemented with Electronic Chart Viewer displaying on a screen adequately to S-52 (Specification for Chart Content and Display Aspects of ECDIS) displaying regulation using domestic ENCs(ENC International Hydrographic Office).
Also, the interface to convert output signals from a navigational instrument has been designed and made after analyzing output signals form a Navigational Instrument and NMEA0183, the protocol between electronic devices installed on a ship to display Navigation Information from ECDIS.
