Application of Smart Station Technology for Establish Control Network Points

Abstract

The paper presents an application of smart measurements for establishing control network points using a Smart Station set offer by Leica. This set may provide measurements in a terrestrial surveying system and in a satellite navigation system separately or in a mixed (hybrid) use of both systems. The procedure used for creating the points was supported by two types of GNSS satellite positioning (fast static and RTK/RTN) methods and with one integrative (hybrid method realized using both terrestrial and satellite surveys) measurement method. In the results from determining the coordinates of control points using multivariate surveys (tacheometry and real-time GNSS methods), the highest differences of coordinates were no more than 0.02 m in the horizontal plane and no more than 0.04 m in vertical plane. As reference data, model coordinates of control network points determined using static GNSS occupation were used. The reference coordinates were calculated using rigorous adjustment with support of observation files from the post-processing service of the national continuously operating reference system. In accordance with the results of the study to survey the control network points in an urban environment, Smart Station equipment is used for the established geodetic data and for other engineering measurement tasks.
