네트워크 RTK 환경에서 대류권 지연변칙 감시를 위한 기법의 타당성 분석

Abstract

Network RTK technique generates corrections by using differenced measurements from reference stations in a network and provides them to rover. The rover, generally, uses a linear interpolation method which assumes that the corrections at each reference stations are spatially correlated. In real case, however, tropospheric delay as a function of the weather conditions can cause a spatial decorrelation characteristic by local climate change. A non-linear characteristic of tropospheric delay can deteriorate Network RTK positioning solution and need to be monitored. So, feasibility study of the method for monitoring the non-linear characteristic of tropospheric delay on Network RTK is performed.
