Closed-form and iterative weighted least squares solutions of Helmert transformation parameters
Journal of Geodetic Science, 2013 The Helmert transformation is the most common transformation between different geodetic systems. In 2-D, in contrast to higher dimensions, it is a well-known procedure how to determine the 4 transformation parameters in a closed form.

Geo-spatial Information Science, 2023 In this paper, we propose an approach to determine seven parameters of the Helmert transformation by transforming the coordinates of a continuous GNSS network from the World Geodetic System 1984 (WGS84) to the International Terrestrial Reference Frame ...

Orbit fitting based on Helmert transformation
Geo-spatial Information Science, 2009 Orbit fitting is used in many GPS applications. For example, in Precise Point Positioning (PPP), GPS orbits (SP3 orbits) are normally retrieved either from IGS or from one of its Analysis Centers (ACs) with 15 minutes’ sampling, which is much bigger than the normal observation sampling.

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.
