Toward a new strategy for multi-technique combined series of EOP and TRF
Résumé
Since 2005 the Groupe de Recherche de Géodésie Spatiale (GRGS) provides on a routine basis series of EOP and station coordinates from combined VLBI, GPS, SLR and DORIS geodetic techniques. The data processing of these techniques is made with unique software: GINS and with the same standards which guaranty homogeneity. Generated normal equations are then combined and solved with the DYNAMO software package The presentation will emphasized the way of processing, and particularly the strategy of merging common EOP and TRF parameters. We will discuss as well the interest of combining tropospheric delay parameters for the electromagnetic signals. Solutions are compared with those derived from International Services as well as from IERS.
