[Termes IGN] station permanenteRésumé : (auteur) We have demonstrated the possibility of deriving both station coordinates and Earth Orientation Parameters (EOP) using weekly normal equations derived from the processing of different space-geodetictechniques: VLBI, SLR, LLR, DORIS and GPS. 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.

[Termes IGN] orbitographieRésumé : (auteur) The long-term stability of the scale of Terrestrial Reference Frames is directly linked with station height determination and is critical for several scientific studies, such as global mean sea level rise or ocean circulation with consequences to global warming studies. In recent International Terrestrial Reference Frame (ITRF) solutions, the DORIS technique was not considered able to provide any useful information on scale (derived from VLBI and SLR). We have analyzed three different DORIS time series of coordinates (GSFC, IGN/JPL, LEGOS/CLS) performed independently using different software packages. In the long-term, we show that the DORIS technique, due to its very stable and geographically distributed network, has extremely good stability ( Numéro de notice : C2005-041 Affiliation des auteurs : IGN+Ext (1940-2011) Thématique : POSITIONNEMENT Nature : Communication nature-HAL : ComAvecCL&ActesPubliésIntl DOI : 10.1007/978-3-540-49350-1_23 En ligne : https://doi.org/10.1007/978-3-540-49350-1_23 Format de la ressource électronique : URL article Permalink : https://documentation.ensg.eu/index.php?lvl=notice_display&id=102721

[Termes IGN] positionnement par DORISRésumé : (auteur) The DORIS system was initially developed for precise orbit determination and precise positioning on the Earth. In continuation of the DORIS Pilot Experiment initiated in 1999, the International DORIS Service (IDS) officially started on July 1, 2003 as an IAG Service after an official acceptance from the IAG Executive Committee at the IUGG General Assembly in Sapporo, Japan. Following this decision, the IERS Directing board accepted the DORIS Service as a new IERS external service. Six satellites carrying DORIS receivers are currently in orbit, permanently observed by 56 well-distributed tracking stations. Among these, three satellites (Jason-1, ENVISAT and SPOT5) are equipped with the new generation of DORIS receivers and were launched between December 2001 and May 2002. The DORIS receivers on these three spacecraft include a navigation function, called DIODE. The permanent tracking network has been constantly improved and specific campaigns of observations have been conducted in Wettzell, Gads and in Antarctica. Recent DORIS performances for precise positioning were improved by this large increase in the satellite constellation, leading to almost 1 cm precision for weekly station coordinates. Significant improvements were also obtained in Polar Motion estimations, leading to 1.0–1.5 mas daily results. In 2003 and 2004, several steps were taken to improve the operations of the IDS, as well as its international cooperation, by organizing several specific analysis campaigns. The International DORIS Service has now started its scientific activity on a routine basis for the International Earth Rotation and Reference Systems Service (IERS) and the Global Geodetic Observing System (GGOS).

Titre : The proposed International DORIS Service Type de document : Article/Communication Auteurs : Pascal Willis Editeur : Berlin, Heidelberg, Vienne, New York, ... : Springer Année de publication : 2005 Collection : International Association of Geodesy Symposia, ISSN 0939-9585 num. 128 Conférence : IAG 2003, International Association of Geodesy General Assembly 30/06/2003 11/07/2003 Sapporo Japon Proceedings Springer Importance : pp 207 - 213 Note générale : bibliographie Langues : Français (fre) Résumé : (auteur) In 1999, an International DORIS Experiment was initiated under the aegis of the International Association of Geodesy. Since then, 3 new DORIS satellites have been launched carrying improved Doppler receivers. In addition, the DORIS tracking network has also been steadily improved. In 2001, a DORIS analysis campaign was launched. Several groups participated using different software and providing weekly and monthly time series of results, making them available on Internet. The goal of this paper is to discuss the status of the DORIS Pilot experiment, to analyze the progress made during the past 2 years and to propose the official creation within the IAG of an International DORIS Service (IDS). Such a service would operate in conjunction with the already existing IGS, IVS and ILRS as part of the proposed International Global Geodetic Observing System (IGGOS).

Titre : Combination of space geodesy techniques for monitoring the kinematics of the Earth Type de document : Article/Communication Auteurs : David Coulot Editeur : Société française d'astronomie et d'astrophysique SF2A Année de publication : 2004 Conférence : SF2A 2004, annual meeting of the French Society of Astronomy & Astrophysics 14/06/2004 18/06/2004 Paris France OA Abstracts only Langues : Anglais (eng) Résumé : (auteur) The main goal of this work is to prove the efficiency of space technique combinations for computation of Earth’s Orientation Parameters (EOPs) and Terrestrial Reference Frames (TRFs). We use four techniques (SLR, DORIS, GPS and VLBI) and the parameters of interest are polar motion, universal time and nutation corrections with a 6-hoursampling and station positions with a weekly sampling. In order to calibrate our method we carry out two combinations. The first one is made directly on measurements and the second one is based on individual solutions.
