Preliminary Velocity Field

Jan 13, 2015

During the period 2011-2014, the WG has combined individual weekly solutions from several contributors and then stacked these weekly combined solutions in order to derive a cumulative position and velocity solution as well as associated residual position time series. The results have been presented at several meetings. This combination was succesfull and promising but the main drawback is a mix of antenna calibration models. More details are given in the conclusion.

Therefore a final combination will be performed based on IGS repro 2 solutions and densification solutions consistent with the IGS repro2 setup in 2015.
