After GNSS has been used for surveying purpose since 1995, many researches have studied about improvement of GNSS accuracy. As a result of these researches, nowadays, the RTK (Real-Time Kinematic) becomes common equipment for the cadastral survey measurement in Korea. In addition, RTK makes it possible to use in open area for the urban planning and the readjustment of fields. RTK makes possible centimeter accuracy in cadastral survey but it may have lower accuracy by means of several types of reasons such influence of the satellite ephemeris, ionosphere, and troposphere. To overcome this low accuracy, the new RTK GNSS System called VRS has been developed, VRS determine the precise location using virtual reference point and DGNSS method. In this paper, we propose how to apply Network-RTK in detail measurement with experimental research.
