Transformation of GDA94 coordinates that have been derived through GNSS CORS.
Concatenation of ITRF2014 to GDA2020 (1) (CT 8049) and GDA94 to GDA2020 (1) (CT 8048). Scale difference in ppb and rate in ppb/yr where 1/billion = 1E-9 or nm/m. See ITRF2014 to GDA94 (2) (CT 9683) for alternative for Australia with distortion modelling.
