Length Variations of European Baselines Derived from VLBI and GPS Observations

Results of VLBI and GPS observations were analyzed with goal to investigate differences in observed baseline length derived from both techniques. VLBI coordinates for European stations were obtained from processing of all available observations collected on European and global VLBI network. Advanced model for antenna thermal deformation was applied to account for change of horizontal component of baseline length. GPS data were obtained from re-processing of the weekly EPN (European Permanent GPS Network) solutions. Systematic differences between results obtained with two techniques including linear drift and seasonal effects are determined.

Computation of a homogeneous coordinate time series for European GPS stations by reprocessing of the weekly EPN solutions

Weekly coordinate time series for the all EPN (European Permanent GPS Network) stations for the period of observations beginning from GPS week 834 was obtained by a reprocessing of the official EPN solutions. Comparison of this series with EPN Central Bureau (EPN CB) and the previous IAA two-year solution for selected EPN stations obtained by reprocessing of the original observations is performed. Results of comparison show that new solution based on fiducial-free strategy is most likely free of seasonal errors. Now the new IAA EPN solution is being computed regularly (on availability of the official EPN solution) and is available to any interested group.
