Karl-Rudolf Koch

Karl-Rudolf Koch (born 30 July 1935 in Hilchenbach, Province of Westphalia) is a German geodesist and professor at the University of Bonn (FRG). In the global geodetic community, he is well known for his research work in geodetic statistics,^[1] particularly robust parameter estimation and in gravity field models.
