The IERS Conventions (2010): Reference Systems and New Models
Abstract
The IERS Conventions (2010) provides the international standard for models to be used in the generation of celestial reference systems (CRS), terrestrial reference systems (TRS), and the Earth orientation parameters (EOPs) that relate the associated reference frames. The models in the new Conventions provide significant improvements when compared to the models of the previous IERS Convent ions (2003). This presentation will provide an overview of the latest adopted models and standards, which include: numerical standards, reference systems, transformations between systems, geopotential, displacement of reference points, tidal variations, atmospheric propagation delays, and relativistic models. This presentation will also compare the current models to the previous models and provide quantitative estimates of the improvement. Finally, the presentation will conclude by providing future plans for the Conventions.
