This article presents the results of the experimental research into the ionospheric influences on the accuracy of the GNSS measurements by comparing single and dual frequency GNSS observations. In the research, GNSS data from three reference stations in central Poland were used. The selection of the observation period depended on the calm and disturbed ionospheric conditions. The purpose of the research was to determine the differences between the control coordinates of the stations and the coordinates of these stations received after processing the results of single and dual frequency GNSS observations. For a better visibility, these differences were presented as horizontal and vertical components. The values of these components are compared with the global magnetic activity and regional ionospheric index I95. The results obtained show that the ionosphere has a considerable impact on single frequency GNSS measurements according to the geodetic requirements, although this impact depends more on the state of ionosphere rather than on its space-time changes.
