Oral presentation

Seven IVS Analysis Centres provide their solutions to the official IVS
contribution to the ITRF2008. The input to the combination process are
sets of datum-free normal equations in SINEX format containing
coefficients for station positions and EOP. All contributions are completely reprocessed from 1984 till 2008 following homogeneous analysis options according to the IERS Conventions and VLBI-specific constants such as axis offsets and reference temperatures.
In this presentation, we explain the combination methodology and give an overview of the principles of data selection. Furthermore, the status and some results of the different contributions are presented.
