Abstract

In this paper, an automatic cruise system of unmanned boat was developed for surveying water depth in reservoir using accurate location information. Using global satellite navigation system(GNSS) data in real time, this unmanned system, combined with an echo sounder, can simultaneously collect location information and depth information on the reservoir. This automatic navigation system allows the automatic route generation program to automatically generate a cruise route according to the input conditions for grid sizes of 5m, 10m and 20m, and automatically controls the cruise route with high positional accuracy. The developed system was tested to verify the applicability of the selected Yonggok(Geoncheon) reservoir as a test reservoir located in Suncheon, Jeollanam-do.

본 논문에서는 위성으로부터의 전파를 이용해 지상의 위치를 측정하는 글로벌 위성항법시스템(GNSS)과 음향측심기를 같이 사용하여 저수지의 정확한 위치 정보와 수심 정보 데이터를 동시에 획득할 수 있는 무인 조사 시스템을 개발하였다. 이 시스템은 자동 경로 생성 프로그램으로 5m, 10m 및 20m의 그리드 크기에 대한 입력 조건에 따라 자동으로 순항 경로를 생성토록 하였고, 또한 자동으로 정확한 순항 경로를 제어하도록 하였다. 개발된 시스템은 전라남도 순천시 서면에 위치한 용곡(건천) 저수지에서 적용 가능성을 검증하였다. 61.1ha의 전체 저수지 수역 조사 시간에 대한 검증 결과는 새로운 시스템이 매우 높은 품질의 공간 분해능을 포함하여 저수지의 수심을 신속하게 조사할 수 있음을 나타내었다.
