Head Office of Geodesy and Cartography (GUGiK)

On October 21-22, 2025, a technical meeting of the European Position Determination System (EUPOS) was held in Berlin, bringing together public entities operating reference station systems in Europe.

During the meeting, the current directions of development of GNSS positioning and navigation support systems and the challenges faced by administrators and users of these services were discussed.

The main topic was GNSS signal interference observed in reference station systems in various countries and ways to eliminate its impact on the quality of correction data provided to users. Suppliers of software for monitoring such interference presented their solutions, which allow the detection of interference in signals received by GNSS receivers operating at reference stations and reduce its impact on the services provided.

The meeting took place at the Berlin Senate headquarters. One of the few laboratories performing individual GNSS antenna calibrations is also located there. Participants learned about the work carried out in the laboratory and saw the robot station used to determine antenna calibration parameters.

The hybrid meeting was attended by about 30 reference station network administrators from across Europe, representatives of scientific institutions, the military, and invited manufacturers of GNSS signal monitoring solutions.

The ASG-EUPOS system, operated by he Head Office of Geodesy and Cartography (GUGiK), was represented by chief specialist Szymon Wajda, who presented the status of the ESA project on the GNSS signal monitoring system in Poland, implemented in cooperation with the National Institute of Telecommunications. The current status of the ASG-EUPOS system and ongoing development activities in the field of GNSS infrastructure were also presented.
