Examination and Evaluation of Results of the National Wide Horizontal Network Adjustment

This paper focuses on examining and evaluating recent results of the national wide horizontal network adjustment which has carried out with respect to the Korean Geodetic Datum 2002 (KGD2002). To do this, 137 geodetic control points were observed by modem GPS technology. After processing all the observations, their outcomes are compared with ones provided by the national wide network adjustment. Results of GPS network show that RMSE is ${\pm}2.7cm\;and\;{\pm}6.5cm$ in horizontal and vertical component, respectively. On the other hand, ones from comparison with EDM network indicate that RMSE is ${\pm}3.0cm$ in horizontal component.
