  ITRF2014 : Frame Definition

Origin:

The ITRF2014 origin is defined in such a way that there are zero translation parameters at epoch 2010.0 and zero translation rates between the ITRF2014 and the ILRS SLR long-term solution obtained by tacking the ILRS time series.


Scale:

The ITRF2014 scale is defined in such a way that there are zero scale and scale rate between ITRF2014 and the average of VLBI and SLR scales/rates.


Orientation:

The ITRF2014 orientation is defined in such a way that there are zero rotation parameters at epoch 2010.0 and zero rotation rates between the ITRF2014 and ITRF2008. These two conditions are applied over a core network (see section transformation parameters between ITRF2014 and ITRF2008)
