Geodetic CRS: ETRS89-GBR [OSNet v2009]
Datum: OSNet v2009
Ellipsoid: GRS 1980
Prime meridian: Greenwich
Data source: EPSG
Information source: IOGP
Revision date: 2026-02-10
Scope: Merging of spatial data referenced to different national realizations of ETRS89 at the sub-decimetre level of accuracy.
Remarks: Derived from concatenation of ETRS89-GBR [OSNet v2009] to ETRF97 (1) (CT code 11010) with ETRF97 to ETRF2000 (2) (CT code 11228) reduced to epoch 2009.756. Scale difference in ppb and scale difference rate in ppb/yr where 1/billion = 1E-9 or nm/m. Accuracy is approximately 1cm at the ETRS89-GBR [OSNet v2009] anchor epoch of 2009.756 but deteriorates with time due to tectonic deformation and/or glacial isostatic adjustment.
Method: Time-dependent Position Vector tfm (geocentric)
