Recently, communication equipment (satellite communication appliance, digital communication appliance) and Navigation equipment are high value-added industries which need advanced satellite and digital technologies in maritime industries.
According to a vessel conveniences regulation, Gyro-Compass installed in 500T over ship, it is a presentation that standard by International convention for the Safety of Life at Sea and IMO resolution A.422(ⅺ ) of International Maritime Organization.
The NMEA(National Marine Electronics Association) converter interface between Gyro-Compass Output Signal and the others marine equipment, it is play to the NMEA data format change.
NMEA is dedicated to the education and advancement of the marine electronics industry and the mark which it serves.
It is non-profit association composed of manufacturers, distributors, dealers, education institutions, and others interested in peripheral marine electronics occupation.
The NMEA standard defines an electrical interface and data protocol for communication between marine instrumentations.
NMEA converter system is a designed of set up three-type format input signal, if a input to signal, possibility interface between Gyro and other marine equipment, NMEA-0183 standard output to interface other marine equipment.
In this study, I produced the NMEA converter system using AT89C52 microcontroller in ATMEL Inc. and expected Gyro-Compass direction sensor, monitoring Synchro input signal through NMEA converter system, it make confirmed interface between Gyro Compass and other marine equipment AIS. at the time, using RS-422 serial communication of ICE61162-1, 61162-2 digital interface.
Today, NMEA converter system used import the most companies of Germany, Russia and other country, it is not korea. in this thesis, suggest the design and implement of NMEA converter system. Thus it will be good for basic research data to produce NMEA converter system ourselves.
