Evaluation of the usefulness of the "millimeter GPS" system for determination of elevations of points in topographic surveys

Commencement of the ASG-EUPOS national network in 2008 resulted in rapid development of utilisation of satellite technologies for topographic surveys. Surveying experiments, performed in 2008 and 2009 at the chair of Engineering Geodesy and Topographic Surveys pointed to high usefulness of the RTK technology for topographic surveys. Research works, carried out at the surveying test site close to Grybów at the Nowy Sącz District, performed with the use of NAWGEO services of the ASG-EUPOS network proved that the expected maximum mean errors of horizontal locations and the ellipsoidal elevation of points, may be of the order of approximately 0.04m and 0.06 m, respectively (Malarski et al., 2010). Considering additional errors of the quasigeoid model, the issue is to obtain the centimetre accuracy in the system of normal elevations, which is required for topographic surveys. It seems that the proposal of Topcon company, concerning the mmGPS technology (Millimeter GPS) may meet those requirements.
