Position determination of control network points in the Smart Station technology using ASG-EUPOS system

Paper covers experiment results concerning usefulness of Leica Smartstation® for detailed horizontal and verical surveying. The experimental work was carried out in the university campus Kortowo during the modernization of ASG-EUPOS permanent station (especially in the northeastern territory of Poland, in June 2011). The analysis was performed to check the performance of this system for setting the control network points in this area. Each control point coordinates were determined using RTK real time service called NAWGEO (VRS, MAC and POJ). Obtained coordinates were compared to the results of static surveys (taken as the reference coordinates) in the system PUWG “2000” and Kronsztadt’86. Analyzed coordinate differences confirmed the characteristic accuracy of the RTK GNSS techniques. Reported accuracy of measured control points in most cases are in line with GUGiK recommendations.
