Scope: Geodesy.

Remarks: This transformation is an operation pipeline consisting of (i) a Time-dependent Coordinate Frame rotation (geocen domain) (method code 1056), and (ii) Geocentric translations using XYZ velocity grid (method code 1159). Step #1 is equivalent to ITRF2008 to ITRF2014 (code 7790), but using the Coordinate Frame rotation convention. Step #2 uses the INADEFORM deformation model to change coordinates from SRGI2013 initial frame reference epoch 2012.0 to static snapshot epoch 2021.0. Accuracy evaluated over this 9-year period at 402 continuously operating GNSS stations is 0.01m/yr (0.0040 m/yr, 0.0103 m/yr and 0.0042 m/yr for X, Y and Z components respectively). Although the interpolation CRS is given as dynamic SRGI2013, any static snapshot including SRGI2013 epoch 2021.0 may be used for interpolation of the deformation grid.

Method: Time-dep Coordinate Frame (geocen) & Geocen translations by XYZ vel (INADEFORM)
