초록

다른 응용분야에 비하여 개략적인 성능을 요구했던 해양 분야에서도 최근 들어 항만 영역에 따라 수치적으로 구체화된 성능을 요구하고 있고, 측위 정확도뿐만 아니라 무결성, 연속성, 가용성 면에서도 보장을 요구하고 있다. 현 DGPS 기준국의 서비스를 사용하는 사용자 입장에서, DGPS 서비스는 아직 IMO에서 요구하는 성능을 모두 만족시키기에 불충분하다. 특히, HEA 영역에서 요구하는 측위 정확도 수준은 대부분 만족하나 무결성 측면에서는 성능을 보장할 수 없다. 본 논문에서는 기존 DGPS 기준국의 감시, 보장, 공지 기능을 강화하여 무결성 측면에서 보강하기 위한 향상된 감시 개념을 제안하고자 한다. 이를 위하여 현재 DGPS 서비스 감시 기능의 취약점을 제시하고 이에 대한 영향을 분석하였으며 이를 토대로 대책을 마련하였다. 본 연구결과는 추후 DGPS 서비스 개선을 위한 기초연구로 활용할 수 있을 것이다.

Even in the marine industry was required the looser positioning performance as compared to other application domain, a high-quality positioning performance and reliability are becoming ever more important. The high-quality performance includes not only accuracy but also integrity, continuity, and availability. However, current DGPS service is not satisfying the minimum positioning performance requirements for maritime user proposed by IMO. Especially, no one can guarantee the required integrity performance by DGPS service. This paper presents the advanced monitoring concept to strengthen the performance of current DGPS through the enhanced monitoring, guarantee and notice functions. To this, the limitations of the integrity monitoring function of current DGPS are analyzed, and a countermeasure is prepared to improve the limitations of the current integrity monitoring function. This paper can be applied as basis research to improvement of the DGPS service.
