Strengthes and Limitations of the ITRF: ITRF2005 and Beyond detected. Possible causes of this inconsistency include the poor SLR and VLBI networks and their co-locations, systematic errors and possible inconsistent model corrections used in the data analysis of both techniques. As conclusion of this paper, some recommendations for improvements of future ITRF solutions are addressed.

Influence of Time Variable Effects in Station Positions on the Terrestrial Reference Frameransformation parameters. This is done with respect to discontinuities (caused e.g. by instrumental changes or earthquakes) or periodic signals such as annual variations. This information is then used to compute a second improved iteration of technique multi-year solutions, where these effects are taken into account.

Combining One Year of Homogeneously Processed GPS, VLBI and SLR Datalthough non-continuous VLBI observations complicate the situation for Universal Time (UT). Finally, the potential of connecting GPS and SLR by estimating degree one spherical harmonic coefficients of the Earth’s gravity field is analyzed.

Günter Müller-Stewens,Gunnar Pautzkearth’s geometry are reflected by vertical and horizontal displacements of geodetic markers. Usually the effect of loading on crustal deformation is computed by means of a weighting function which is based on site-independent load Love numbers (Green’s function). But as the Earth’s crust is composed
