Geodetic CRS: ETRF2005
Datum: European Terrestrial Reference Frame 2005
Ellipsoid: GRS 1980
Prime meridian: Greenwich
Data source: EPSG
Information source: IOGP, from EUREF Technical Note 1: Relationship and Transformation between the International and European Terrestrial Reference Systems.
Revision date: 2026-07-21
Scope: Merging of spatial data referenced to different national realizations of ETRS89 at the sub-decimetre level of accuracy.
Remarks: Derived from concatenation of ETRF2005 to ITRF2005 (CT code 5900, with direction reversed) reduced to epoch 2000.00 and ITRF2005 to ETRF2000 (CT code 7950). Scale difference in ppb and scale difference rate in ppb/yr where 1/billion = 1E-9 or nm/m.
Method: Time-dependent Position Vector tfm (geocentric)
Area of use: Europe - onshore and offshore - ETRF extent - approximately 16°W to 33°E and 33°N to 84°N.
