The present paper reported on the development of the prototype coastal navigation support system, using personal computer (TEAC, PS-80) which recently became popular. The system has been constructed for the purpose of load reduction in chart works (ship positioning), so navigator will be released from chart works to keep more careful look out for safe ship operations. The system has the following functions; (1) The system indicates target name, bearing and distance on the CRT display. (2) The informations of ship course and speed are given by gyrocompass and electromagnetic log through A/D converter or by keyboard. (3) The system calculates the ship position from more than two target bearings. (4) The system indicates observed position and dead reckoning position with time on the CRT display. (5) The system indicates name, bearing and distance of next course changing point on the CRT display. (6) Using X-Y ploter, the ship positions are drawn on chart.
