Abstract
Recently, it was required many efforts to get no person operating ship and more safety using of digital communication and automation of navigation. One of them is double clauses of shipborne equipment.

By International convention for the Safety of Life at Sea(SOLAS) and IMO resolution A.382(X) of International Maritime Organization(IMO), it was obligated that standard magnetic compass is installed in ship, as double clauses of shipborne equipment.

That is, it was generalized that gyro compass which is exact device indicating true north is installed in ship for long time ago, but it was recommended obligatory that standard magnetic compass operated independently is installed for safety.

Also, it was recommended obligatory that transmitting heading device(THD) transmitting heading information to shipborne equipment such as radar and Automatic Identification System(AIS) is installed in 300~500T ship, by IMO resolution MSC.116(73)

Following above clauses, Transmitting Magnetic Compass(TMC) system as a efficiently method of THD using standard magnetic compass was used widely, and was begun to install in ship which was dehydrated after July 1. 2002.

TMC system is device which was inputted magnetic signal from fluxgate sensor connecting magnetic compass, and then displaying heading information processed correcting deviation and variation necessary in display part, and outputting suitable heading signal to communicate other navigation equipment through NMEA(National Maritime Electronics Association standard in the sea.

Today, TMC system permitted international approval is produced in minority companies of Germany and several country, it is not yet in Korea

In this thesis, suggest the design and implement of TMC system. Thus it will be good for basic research data to produce TMC system ourselves.

In this study, I produced the TMC system using 80C196 microcontroller in Intel Inc. and excepted making of fluxgate sensor, using common product C_Plath of Germany.

Heading signal inputted sensor is processed by suitable algorithm, and then heading information processed is been transmitting to display part and at the same time, sending the NMEA-0183 standard output to communicate other navigational equipment.
