Abstract

For improvement of network RTK performance in survey field, Spatial Information Research Institute (SIRI), LX Korea Cadastral Survey Corporation installed 30 GNSS permanent stations in Korea Peninsula, and has been running the MAC-based network RTK service as a test version. In this paper, we introduce the LX GNSS network and analyze the positioning accuracy of the LX MAC RTK service. For field test of the LX MAC RTK service, we installed temporally fixed anchor points and observed simultaneously with VRS of National Geographic Information Institute. As a result, the horizontal position differences and initial times of LX MAC with respect to NGII VRS are $1{\sim}2{\pm}1cm$ and <10 seconds, respectively.

대한지적공사 공간정보연구원에서는 네트워크 RTK의 효율성을 향상시키기 위하여 전국에 30개소의 LX 위성측위 인프라를 구축하고 MAC 기반의 네트워크 RTK 서비스를 시험운영하고 있다. 본 논문에서는 LX 위성측위 인프라의 구축 현황을 소개하고 MAC 기반의 네트워크 RTK 서비스의 측위 성능 분석 결과를 기술하였다. 성능 분석을 위하여 임시 고정점을 설치하고 국토지리정보원의 VRS와 동시관측을 실시하였다. 그 결과 두 인프라는 동서, 남북 방향으로 평균 $1{\sim}2{\pm}1cm$ 차이를 보였으며, 초기화 시간도 10초 이내에서 근소한 차이를 보였다.
