Feodosy Krasovsky

Feodosy ( Theodor ) Nikolayevich Krassowski (Russian Феодосий Николаевич Красовский; . * 14 Septemberjul / September 26 1878greg in Galich, . † October 1, 1948 in Moscow) was a Russian mathematician and surveyor, in particular in the field of Geodesy and Adjustment Theory researched.

In the West he was known mainly by the calculated in the late 1930s Krasovsky ellipsoid whose parameters in 1940 he published ( equatorial axis 6378.210 km and Earth flattening 1:298,6 ). It represents the state of the art at the time the determination of the mathematical figure of the earth and was declared after World War II by the Soviet Union for the computational basis of all land surveys in the Eastern world ( some countries have now returned to the system ED50 ).

Krassowski (often also written Krassovsky or Krassowskij ) made ​​use of for these calculations, many of the global data available to it, including those of the Bessel ellipsoid, but with a focus on the networks of the Soviet Union. Therefore, its ellipsoid is the geometric relationships of Eurasia adapted particularly well (see also the geoid and earth curvature ).

Among his approximately 100 other publications also affect some western research and survey projects, including the geodesic Baltic Ring ( Baltic Ring ) and various reducing and balancing method of Geodesy.
