(null/copy) Approximation for medium and low accuracy applications assuming equality between plate-fixed static and earth-fixed dynamic CRSs, ignoring static/dynamic CRS differences.
Parameter values from NGO 1948 to ETRS89 (1) (code 1653). Assumes ETRS89 and WGS 84 can be considered the same to within the accuracy of the transformation.
