Geodetic CRS: Pulkovo 1995
Datum: Pulkovo 1995
Ellipsoid: Krassowsky 1940
Prime meridian: Greenwich
Data source: EPSG
Information source: GOST R 51794-2001, approved by GosStandard of Russia Decree #327 of August 9, 2001.
Revision date: 2020-03-14
Scope: Transformation of coordinates at 1m level of accuracy.
Remarks: Derived through concatenation of Pulkovo 1995 to PZ-90 (1) (tfm code 1257) and PZ-90 to WGS 84 (2) (tfm code 1244). Mandated for use in Russia by GOST R 51794-2001, but this has been superseded by GOST R 51794-2008. Replaced by tfm code 5043.
Method: Coordinate Frame rotation (geog2D domain)
Area of use: Russian Federation - onshore and offshore.
Description: (24.82, -131.21, -82.66, 0.0, 0.0, -0.16, -0.12)
