To acquire coordinates of underground facilities and road and road facilities that are the basic data of urban information system, the control point surveying must be performed first. there are a lot of studies about control surveying and detail surveying using GPS which offers uniform accuracy in wide area rapidly. Control surveying using GPS needs lots of time and efforts in exploring and occupation the nation control points because the present GPS procedure use fixed points with data received on the nation control points. In this study we analyze accuracy according to baseline and number of GPS continuous stations. Consequently the case which use fixed point with two close range GPS continuous stations shows the best result.
