The paper presents the structure, performance and preliminary results of new ionosphere monitoring service over the ASG-EUPOS network of GNSS reference stations in Poland. This dense permanent network consisting of ~110 stations is a part of the European Position Determination System (EUPOS) project involving 18 countries of Central and Eastern Europe. The service was developed at the University of Warmia and Mazury in Olsztyn and as one of few uses the undifferenced carrier phase measurements from dual-frequency receivers for modeling of the ionosphere. It provides ionosphere maps (TEC) with spatial resolution of 0.25×0.25 degrees and with temporal resolution of 5 minutes. In addition, the service provides daily and monthly differential code bias (DCB) values for each of the GNSS receivers of the ASG-EUPOS system. The DCBs are estimated based on phase-smoothed pseudoranges.

Keywords: ionosphere; TEC; ionospheric delay; GNSS.
