측위/항법/시각(Positioning, Navigation, and Timing: PNT) 정보는 교통, 측량, 통신, 국방 등 다양한 분야에서 사용되는 정보로 각국은 이를 주요한 국가 정보인프라로서 파악하여 체계적으로 구축하고 있다. 위성항법시스템으로 대표되는 PNT 체계의 국내외 현황에 대해 살펴보고 국내 PNT 체계 발전 방안을 검토해본다.

국제수로기구(IHO)는 수로데이터의 상호 운용성 확보 및 활용 증진을 위해 ISO 19100 지리공간 정보 표준을 수로분야로 확장하여 S-100(범용수로데이터모델) 표준을 개발하여 현재 2.0 버전에 이르고 있으며, S-101 차세대 전자해도 표준을 포함하여 전자서지 및 동적 수로정보 등의 다양한 표준을 개발 중이다. 한편, 국제해사기구는 e-Navigation 전략 추진을 위해 전략이행계획(SIP)를 개발하고, e-Nav 정보표준인 CMDS를 S-100 표준을 기반으로 개발하기로 결정 하였으며, 국제항로표지협회는 AtoN, IVEF, AIS-ASM, 측위 인프라에 관한 S-20X 표준개발을 진행하고 있다. 우리나라의 해양조사 및 수로도서지 간행을 담당하고 있는 국립해양조사원은 S-100 표준 기술을 확보하고 국가 수로국으로의 역할 수행을 위해 S-100 수로데이터를 구축할 계획으로 있다. 본 연구에서는 S-100/S-10X 표준개발 현황 및 우리나라의 차세대 전자해도 개발 계획을 검토하고, 해사안전, e-Navigation 및 VTS 분야 관점에서 시사점을 정리 하였다.

According to the developing advanced techniques and removal of Selective Availability, much research has been conducted to improve the accuracy of GPS positioning in absolute and relative mode by estimating the nuisance parameters such as atmospheric effect, clock errors and multipath. Especially, the continuous effort of establishing the CORS in many countries and the effort of ICS making effective global networking make more application areas and the necessity of more precise location is being increased. Some of the countries like German, Japan and Swiss already utilized the Virtual Reference System for better location accuracy and services. In this study, the VRS system is investigated in terms of system principle, required H/W and S/W, management and operation, revision of related law, expected application and market etc. and find optimal solution in each aspect for economic and fast set up of the system in this country. The analysis of Korean CORS, communication infra and market estimation is performed for the efficient system establishment. Also. the suggestion on the advertisement and education of the system is also included. It is expected that this study contributes for the establishment of effective and precise nationwide location service so that many SOC areas including navigation, GIS, Telematics, LBS can provides better service for the users.

Korea has established an advanced infrastructure for real-time precise positioning such as CORS, virtual reference station service and perform continuous upgrading. However, in order to utilize the national infrastructure, it is necessary to process the acquired spatial information and take many steps to derive the final product. In addition, this process is highly dependent on foreign software. In this study, GNSS field survey system was developed and evaluation of its usability was performed. Real-time GNSS field survey system was developed and the system improves user̓s convenience and usability. The system was able to conduct survey effectively and produce the results. In addition, we compare the existing software with the survey performance to show the availability of the real-time GNSS surveying system. The system developed through the research can perform all the functions from real-time survey to the production of the outputs. It can create economical added value of the foreign software as a whole and simplify the work required for post-survey performance.
