[Termes descripteurs IGN] série temporelleRésumé : (Auteur) Significant differences in time series of geodynamic parameters determined with different Global Navigation Satellite Systems (GNSS) exist and are only partially explained. We study whether the different number of orbital planes within a particular GNSS contributes to the observed differences by analyzing time series of geocenter coordinates (GCCs) and pole coordinates estimated from several real and virtual GNSS constellations: GPS, GLONASS, a combined GPS/GLONASS constellation, and two virtual GPS sub-systems, which are obtained by splitting up the original GPS constellation into two groups of three orbital planes each. The computed constellation-specific GCCs and pole coordinates are analyzed for systematic differences, and their spectral behavior and formal errors are inspected. We show that the number of orbital planes barely influences the geocenter estimates. GLONASS’ larger inclination and formal errors of the orbits seem to be the main reason for the initially observed differences. A smaller number of orbital planes may lead, however, to degradations in the estimates of the pole coordinates. A clear signal at three cycles per year is visible in the spectra of the differences between our estimates of the pole coordinates and the corresponding IERS 08 C04 values. Combinations of two 3-plane systems, even with similar ascending nodes, reduce this signal. The understanding of the relation between the satellite constellations and the resulting geodynamic parameters is important, because the GNSS currently under development, such as the European Galileo and the medium Earth orbit constellation of the Chinese BeiDou system, also consist of only three orbital planes.

IGS International GNSS Service technical report 2017Adobe Acrobat PDFRecent activities of the GGOS standing committee on Performance simulations and Architectural Trade-Offs (PLATO) / Benjamin Männel (2018)
Titre : Recent activities of the GGOS standing committee on Performance simulations and Architectural Trade-Offs (PLATO) Type de document : Chapitre/Contribution Auteurs : Benjamin Männel, Auteur ; Daniela Thaller, Auteur ; Markus Rothacher, Auteur ; Johannes Böhm, Auteur ; Jurgen Müller, Auteur ; Susanne Glaser, Auteur ; Rolf Dach, Auteur ; Richard Biancale, Auteur ; Mathis Blossfeld, Auteur ; Alexander Kehm, Auteur ; Iván Herrera Pinzón, Auteur ; Franz Hofmann, Auteur ; Florian Andritsch, Auteur ; David Coulot Editeur : Berlin, Heidelberg, Vienne, New York, ... : Springer Année de publication : 2018 Importance : pp 1 - 4 Langues : Anglais (eng) Résumé : (auteur) The Standing Committee on Performance Simulations and Architectural Trade-Offs (PLATO) was established by the Bureau of Networks and Observations of the Global Geodetic Observing System (GGOS) in order to support – by prior performance analysis – activities to reach the GGOS requirements for the accuracy and stability of the terrestrial reference frame. Based on available data sets and simulated observations for further stations and satellite missions the committee studies the impact of technique-specific improvements, new stations, and additional co-locations in space on reference frame products. Simulation studies carried out so far show the importance of the individual station performance and additional stations for satellite laser ranging, the perspectives for lunar laser ranging assuming additional stations and reflectors, and the significant impact of the new VGOS antennas. Significant progress is achieved in processing VLBI satellite tracking data. New insights in technique-specific error sources were derived based on real data from short baselines. Regarding co-location in space PLATO members confirmed that E-GRASP could fulfill the GGOS requirements with reaching a geocenter and scale accuracy and stability of 1 mm and 0.1 mm/year, respectively.
