[Termes IGN] réseau géodésique terrestreRésumé : (Auteur) Since 21 June 1992 the International GPS Service (IGS), renamed International GNSS Service in 2005, produces and makes available uninterrupted time series of its products, in particular GPS observations from the IGS Global Network, GPS orbits, Earth orientation parameters (components x and y of polar motion, length of day) with daily time resolution, satellite and receiver clock information for each day with different latencies and accuracies, and station coordinates and velocities in weekly batches for further analysis by the IERS (International Earth Rotation and Reference Systems Service). At a later stage the IGS started exploiting its network for atmosphere monitoring, in particular for ionosphere mapping, for troposphere monitoring, and time and frequency transfer. This is why new IGS products encompass ionosphere maps and tropospheric zenith delays. This development became even more important when more and more space-missions carrying space-borne GPS for various purposes were launched. This article offers an overview for the broader scientific community of the development of the IGS and of the spectrum of topics addressed today with IGS data and products.

[Termes IGN] station permanenteRésumé : (Editeur) [...] Looking on Wikipedia, we find the following traits necessary for successful collaboration : ”shared'"objectives; sense of urgency and commitment; dynamic process; sense of belonging; open communication; mutual trust and respect; complementarity diverse skills and knowledge; intellectual agility” These words fittingly describe the lnternational GNSS Service (IGS) and how it operates. The IGS was established in 1994 in order to provide the highest quality GNSS data and products in support of Earth science research multidisciplinary application and education. It was and is still the aim of the IGS advance scientific understanding of he Earth system components. And their interactions, as well as to facilitate other applications benefiting society. The IGS consists of over 200 actively contributing organizations in more than 80 countries and a global network of over 370 stations. In addition to providing GPS and, GLONASS raw measurements, the IGS contributes to the maintenance and improvement of the International Terrestrial Reference Frame, produces high accuracy GPS and GLONASS satellite orbit and clock data, and monitors the Earth's rotation and the state of its ionized and neutral atmospheres. Among other applications, IGS measurements and products help monitor the movement and flexure of the Earth's tectonic plates, assess sea-level variations, carry out precise time transfer, and determine accurate trajectories for low-Earth orbiting satellites. In this month's column, Angelyn Moore, the lGS Central Bureau's deputy director, overviews the organization's service, history, and future, demonstrating that the IGS is a model of scientific collaboration of which not just the GNSS community but the whole world should be proud.

[Termes IGN] station de référenceRésumé : (auteur) Analysing time series of space-geodetic station coordinates, we show that VLBI, SLR and DORIS station motions have a white noise error spectrum, while the majority of GPS station motion have a flicker noise error spectrum. In the latter case, discontinuities in the series do not account for this spectrum. Atmospheric loading has a white noise spectrum, at a much lower level than geodetic measurement errors in the long term. The series of transformation parameters derived for the GPS colocation sub-networks with VLBI, SLR and DORIS have very close spectral characteristics, reaching the 1 mm stability level at one-year interval in a white noise context.
