In this paper, we study on the one-way Network RTK methodologies to solve the problem of VRS(Virtual Reference Station) that is the limited number of simulataneously connected rover and compare the performance of MAC-based Network RTK with that of current Network RTK infrastructure. We’ve constructed temporal reference stations at KCSC (Korean Cadastral Surveying Corp.) branch offices in Ganghwa, Pocheon and Yongin, and the Fishery Resource Insti. in Yeongheung-do in order to include the Ganghwa, Incheon International Airport, and reclaimed land on the West Coast into the Network RTK-available region. Without any authentication, the rover can calcuate its own coordinate so that the feasibility of Network RTK surveying under one-way communication has been proven. From the test at Saet-gang in Yeoeuido and Yeongjong-do in Incheon, the accuracy and time for the initial fix were equivalent to those of the existing servcie, therefore we expect that the one-way Network RTK system can support the heavy load of KCSC rovers that is possibly caused by the future cadastral resurvey project of Korea.
