| Abstract: | Helmert transformation plays an important part in the establishment and maintenance of Terrestrial Reference Frame. The formulae to realize datum definition using Helmert transformation parameters are rigorously derives. Three kinds of transformation formulae are proved to be equivalent in theory.Taking ITRF2005 for example,the effects of Helmert transformation parameters precision on reference transformation of non core stations are analyzed, and results show that maximum residual can be up to several centimeters. |
