ECDIS와 Auto-Pilot을 이용한 자동 항로추적 시스템

Abstract

The Auto-Pilot with heading angle control is used in the ocean. But in the harbor area it is dangerous to navigate using Auto-Pilot with heading angle control. The Auto Route Tracking System is necessary in the harbor area to avoid collision and grounding accident. The Auto Route Tracking System of this paper is composed of ECDIS, Auto-Pilot with heading angle control, Gyro and GPS of the ship. The Auto Route Tracking System is validated using ship handling simulator of KRISO. Two types of Auto Route Tracking System is tested in this paper. One is controlled with heading angle only, and the other is controlled with heading angle and drift angle of ship. The drift angle of ship is calculated by the difference of heading angle from Gyro and advancing angle from GPS. When environmental forces are exerted to ship, the Auto Route Tracking System with heading angle only is failed to keeping the track. But Auto Route Tracking System with heading and drift angles is worked well.
