This paper presents the performance study results of two ASG-EUPOS system services (KODGIS and NAWGIS) carrying out real-time network code DGPS positioning. In this elaboration, basic information about the system and discussed services are presented, as well as the advantages of the code differential positioning. The accuracies of the KODGIS and NAWGIS given by the system administrator are provided and papers and presentations with local and international impact were considered. A description of the experiment and the obtained results were provided for three days of measurements taken in north-eastern Poland, near Olsztyn. The research results showed that the positioning errors achieved using the KODGIS service throughout the study exceeded values declared by the ASG-EUPOS system administrator. This service, with respect to NAWGIS, was also characterized by higher fluctuations in the determined coordinates. Moreover, the occurrence of systematic errors in the performance of both studied services was noted, whereas the weakest element of the entire ASG-EUPOS system appeared to be the data transmission to the user.
