Friedrich Robert Helmert. Professor Friedrich Robert Helmert. Photographer unknown. contribution into geodesy and theory of errors. Technical University in Aachen, University of Berlin. Friedrich Robert Helmert (31 July 1843 – 15 June 1917) was a German geodesist and statistician with important contributions to the theory of errors .
Helmert transformation. The transformation from a reference frame 1 to a reference frame 2 can be described with three translations Δx, Δy, Δz, three rotations Rx, Ry, Rz and a scale parameter μ. The Helmert transformation (named after Friedrich Robert Helmert, 1843–1917) is a geometric transformation method within a three-dimensional space.
This distribution was first described by the German geodesist and statistician Friedrich Robert Helmert in papers of 1875–6, where he computed the sampling distribution of the sample variance of a normal population. Thus in German this was traditionally known as the Helmert'sche ("Helmertian") or "Helmert distribution".
The Faculty of Georesources and Materials Engineering is one of nine faculties at the RWTH Aachen University. It comprises three sections for Raw Materials and Waste Disposal Technology, Metallurgy and Materials Technology and Geoscience and Geology. The faculty was found in 1880 and produced several notable individuals, including Friedrich ...

The Helmert–Wolf blocking ( HWB) is a least squares solution method for the solution of a sparse block system of linear equations. [1] It was first reported by F. R. Helmert for use in geodesy problems in 1880; [2] H. Wolf [ de] (1910–1994) published his direct semianalytic solution in 1978. [3] [4] It is based on ordinary Gaussian ...
Years of service. 1979–2009. Rank. Captain. Unit. J.A.G. Corps. James Andrew Wynn Jr. (born March 17, 1954) is an American jurist.

Least-squares adjustment. Least-squares adjustment is a model for the solution of an overdetermined system of equations based on the principle of least squares of observation residuals. It is used extensively in the disciplines of surveying, geodesy, and photogrammetry —the field of geomatics, collectively.
