SK-42 Reference System
Encyclopedia
The SK-42 reference system also known as the Krasovsky
ellipsoid
, is a coordinate system established in the Soviet Union
in 1942 as Systema koordinat , and provides parameters which are linked to the geocentric Cartesian coordinate system
PZ-90. It was used in geodetic calculations, notably in military mapping and determining state borders.

Cartesian coordinate system
A Cartesian coordinate system specifies each point uniquely in a plane by a pair of numerical coordinates, which are the signed distances from the point to two fixed perpendicular directed lines, measured in the same unit of length...
