SK-42 reference system has been the subject of debate, research and inspiration, and has left an indelible mark on society. From its origins to its relevance today, SK-42 reference system has generated endless discussions and sparked passionate interest in those seeking to understand its meaning and impact on the world around us. Through this article, we will try to shed light on SK-42 reference system and explore the various facets that make it so intriguing and relevant in the current context.
The SK-42 reference system also known as the Krasovsky 1940 ellipsoid, is a coordinate system established in the Soviet Union in 1942 as Systema koordinat (Russian: Система координат 1942 года), 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. The coordinate system SK-42 served as a foundation for developing the SK-63 reference system which was created and used primarily for civilian and industrial development purposes.
The Krasovsky 1940 ellipsoid uses a semi-major axis (equatorial radius) a of 6,378,245 m, and an inverse flattening 1/f of 298.3 : 220
