Geodetic CRS: WGS 84 (G873)
Datum: World Geodetic System 1984 (G873)
Ellipsoid: WGS 84
Prime meridian: Greenwich
Data source: EPSG
Information source: Kelly and Dennis, "Transforming between WGS84 Realizations", Journal of Surveying Engineering 148(2), January 2022 (tables 5 and 6).
Revision date: 2022-05-18
Scope: Spatial referencing.
Remarks: Scale difference in ppb where 1/billion = 1E-9 or nm/m. Derived via ITRF94 through ITRF2000. May be approximated to 0.2m using 7-parameter CF method 1032 with parameters for epoch 1999.50 of tX=1.1mm tY=-8.0mm tZ=14.3mm rX=0 rY=0 rZ=0.05mas dS=1.505ppb.
Method: Time-dependent Coordinate Frame rotation (geocen)
