Current activities of International Association of Geodesy (IAG) as the successor organisation of the Mitteleuropäische Gradmessung / Hermann Drewes in ZFV, Zeitschrift für Geodäsie, Geoinformation und Landmanagement, vol 137 n° 3 (01/06/2012)

Its activities have changed dramatically from its beginning in 1862 till today. While it started with the aim of determining the regional anomalies of the Earth's curvature in Europe by connecting astronomical observatories through triangulation networks, it concentrates now on the observation and modelling of the phenomena and effects of physical processes in the System Earth employing mainly space techniques. The structural and scientific developments over time are summarised, and the present structure and activities are described in detail.

Analysis of the DORIS contributions to ITRF2008 / Detlef Angermann in Advances in space research, vol 46 n° 12 (15/12/2010)

The computation methodology of DGFI is based on the combination of datum-free normal equations (weekly or session data sets, respectively) of station positions and Earth orientation parameters (EOP) from the geodetic space techniques DORIS, GPS, SLR and VLBI. In this paper we focus on the DORIS part within the ITRF2008 computations. We present results obtained from the analysis of the DORIS time series for station positions, network translation and scale parameters, as well as for the terrestrial pole coordinates. The submissions to ITRF2008 benefit from improved analysis strategies of the seven contributing IDS analysis centres and from a combination of the weekly solutions of station positions and polar motion. The results show an improvement by a factor of two compared to past DORIS data submitted to ITRF2005, which has been evaluated by investigating the repeatabilities of position time series. The DORIS position time series were analysed w.r.t. discontinuities and other non-linear effects such as seasonal variations. About 40 discontinuities have been identified which have been compared with the results of an earlier study. Within the inter-technique combination we focus on the DORIS contribution to the integration of the different space geodetic observations and on a comparison of the geodetic local ties with the space geodetic solutions. Results are given for the 41 co-location sites between DORIS and GPS.
