(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 Monte Mario to ETRS89 (3) (code 1663). Assumes ETRS89 and WGS 84 can be considered the same to within the accuracy of the transformation.
