The work is performed in the frame of a joint project within the GRGS, Groupe de Recherches de Géodésie Spatiale, federation of French institutes. Observations of the different techniques: VLBI, SLR, LLR, DORIS and GPS are processed separately at the different institutes where in addition expertise can be found for the specific technique. Before such products are adopted as references, different problems concerning the stabilization of the terrestrial reference frame have to be solved in addition to upgrading the individual techniques processing to the best possible level of accuracy.

Status of the ITRF2005 / Zuheir Altamimi (2006) 

Public contenu dans Journées 2005, systèmes de référence spatio-temporels, Warsaw, 19-21 September 2005 / Alexander Brzezinski (2006)   Titre : Status of the ITRF2005 Type de document : Article/Communication Auteurs : Zuheir Altamimi , Auteur ; Xavier Collilieux , Auteur ; Juliette Legrand, Auteur ; Claude Boucher , Auteur Editeur : Paris, Meudon et Nançay : Observatoire de Paris Année de publication : 2006 Conférence : JSRST 2005, Journées systèmes de référence spatio-temporels, Earth dynamics and reference systems, five years after the adoption of IAU 2000 resolutions 19/09/2005 21/09/2005 Varsovie Pologne OA Proceedings Importance : pp 45 - 47 Format : 21 x 30 cm Note générale : bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Systèmes de référence et réseaux [Termes IGN] International Terrestrial Reference Frame Résumé : (auteur) Unlike the previous realization of the International Terrestrial Reference System (ITRS), the ITRF2005 input data are time series of station positions (weekly solutions from satellite techniques and daily solutions from VLBI) and daily Earth Orientation parameters (EOPs). This paper summarizes the current status of the ITRF2005 in terms of submitted input data and the methodology used to construct the ITRF2005. Since this the first time that EOPs are included in the ITRF combination, we show some EOP preliminary results and in particular comparison to the IERS C04 series. These preliminary EOP results show a significant bias in the Y pole component (of the order of 200 micro-arc-second) between our combination and the C04 series. The ITRF2005 will be the occasion to re-calibrate the C04 results in order to make it consistent with the ITRF2005.
