위성항법시스템의 국내 철도적용시 측위정확성 개선 방안 연구

초록

In this paper, we investigate the scheme to improve the position accuracy using GNSS(Global Navigation Satellite System). Then we configure the real-time DGPS environment with use of NTRIP currently being in service on the DGNSS central office of MLTM(Ministry of Land and Transportation). And we verify the improvement of position accuracy and the continuity of GPS correction data through the DGPS test in Chungbuk line and Joongang line.
