Adjusting a 2D Helmert transformation within a Gauss–Helmert Model with a singular dispersion matrix where BQ is of smaller rank than B [PDF]
Acta Geodaetica Et Geophysica, 2016 The case of a singular dispersion matrix within the Gauss–Helmert Model has been considered before, most recently even allowing the rank of BQ to be smaller than the rank of B. In this contribution the emphasis is shifted towards an illuminating example, the 2D Helmert transformation.

Helmert Transformation of Reference Coordinating Systems for Geodesic Purposes in Local Frames
Procedia Engineering, 2014 The real-time frames may develop a need for data originating from the concrete reference system. Sometimes this can refer to the Gauss-Krüger coordinates and UTM projections with a specific date. This paper analyses the connection between UTM projection with date WGS-1984 and Gauss-Krüger coordinates for a wider area of the City of Rijeka, without a ...
