지적기준점에 대한 GNSS 정지측량에 있어서 관측조건의 변화에 따른 위치정확도 분석

초록

Preparation for the World Geodetic System in Cadastrae field is progressing largely divided into cadastral control point and cadastral map. Since 2021 according to the laws it should be enforced in an all-out World Geodetic System in Cadastrae field. Cadastral re-survey project is reviewed the important work of preparing the World Geodetic System and GNSS survey has become an important way to prepare for the World Geodetic System. In this study, by varying the baseline distance and fixed-point and observation time for the cadastral control points in Daegu, GNSS surveying was accomplished in a variety of environments, and then it was analyzed the positioning accuracy due to changes in observation conditions in the GNSS Static surveying on cadastral control point. It was found through the eesearch results that it is ensured the accuracy of less than 1.5cm within a baseline distance of 30km if the more than three points among the given points is fixed. And, it is ensured the accuracy of less than 1.0cm if four hours observation time is occupied in the GNSS static surveying for the cadastral control points.
