Advantages and obstacles of using basic satellite receivers in measurements was shown in the thesis. On the basis of Multiple measurements of a plot, using handheld GNSS receiver, typical errors have been examined. Outcomes clearly prove that environmental and personal factors have significant influence on the er-rors appearing while performing a survey.

The paper presents results of test measurements conducted with the use of a manual receiver of GPS (Global Positioning System) signals adjusted to the reception of EGNOS (European Geostationary Navigation Overlay Service) cor-rection signal which is theoretically to cover Europe and southern part of Africa with its range. However, it is known that Central and Eastern Europe lies on the border of EGNOS range and some parts of Poland have limited access to signals from this system. Test measurements were conducted on selected stationary points with the use of the receiver produced by Garmin GPSMAP 62s, equipped with MAZO GPS active outdoor aerial. During the measurements, spatial coordinates, their reliability, number of satellites received, time of measurement, accessibility of EGNOS signals were registered. Results of the conducted tests indicate broad possibilities of using manual receivers in measurements mainly for the needs of spatial measurement systems but not only. Yet the reliability of results depends on many factors and on keeping a specific measurement regime. ...
