GPS를 이용한 실시간 선박위치정보시스템 개발

Development of the Realtime Ship Position Information System using the GPS

In this paper, we developed the Realtime Ship Position Information System and the software in relation to the system, which consists of the on-board system and the shore-based system. The on-board system is composed a GPS receiver, a computer, and a modem. The shore-based system is composed of a telephone, a modem and a computer. Both systems are operated by the data communication program The system displays automatically the ship's movement on the digital chart by using the ship's position acquired by a GPS receiver via INMARSAT-A communication system. The results presented in many experiments indicate that the system in processing the position data well during the transmission and reception.
