Abstract
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.
