| Abstract: | The latest realization of the International Terrestrial Reference Frame (ITRF) is the ITRF2014, published by the IERS in January 2016.The ITRF2014 is realized by combining solutions of different space geodesy techniques.In the preparation for ITRF2014, the non-linear motions are modeled for the first time, including the estimation of the seasonal terms and the application of postseismic deformation (PSD) models.The basic information of the datum definition, the input data and the data processing strategy are introduced.And the main improvements of ITRF2014,compared with the previous versions of ITRF, are analyzed. |
