초록

본 논문에서는 국토해양부 해양교통시설과의 연구개발과제인 '광역보정시스템(WA-DGNSS) 구축기술개발' 과제에서 현재까지 개발된 지상국 부분에 대한 성능 검증에 대하여 설명한다. 본 연구개발과제에서는 전국토에 균일한 정확도, 가용성 및 무결성 성능을 보장할 수 있는 광역보정시스템의 핵심알고리듬을 개발하고 지상기반 데모시스템 구축을 완료하여 최종 년도에는 의사위성을 통한 실시간 데모를 실시할 예정이다. 또한 미래 다중 GNSS에 대비하여 GLONASS 및 Galileo를 포함하는 광역보정시스템의 성능을 시뮬레이션을 통해 예측하였다. 본 과제에서 개발된 연구 결과들은 알고리즘 설명서 및 핵심기술권고사항으로 문서화되어 2014년부터 진행될 위성기반 광역보정시스템(SBAS)의 개발에 직접적으로 활용될 예정이다.

This paper describes the progress and results of 'Wide Area Differetial GNSS (WA-DGNSS) Development' project which is supported by Korea Ministry of Land, Transport and Maritime Affairs. This project develops the main algorithm of the WA-DGNSS which can guarantee the improved accuracy, availability and integrity all over the Korean peninsula. After the establishment of WA-DGNSS ground system, a real time demonstration using pseudolite will be conducted. Product of this project will be directly utilized in Korean Satellite Based Augmentation System(SBAS) development project which is planned to be started from 2014.
