| Zusammenfassung |
| The space geodetic techniques GPS, VLBI, SLR, and DORIS can been combined at the level of Normal Equations for recovering geodetic parameters such as terrestrial frame, Earth orientation parameters and celestial frame consistently in a same run. The potential advantage of the method is to improve the accuracy, the time resolution and the overall consistency of the products obtained in the combination. In the frame of the International Earth Rotation and Reference Systems Service (IERS) a Working Group at the Combination Level (WG COL) was set up in the course of 2009. As participant to this Working Group, the GRGS (Groupe de Recherche en Géodésie Spatiale) has developed a combination process at the weekly bases using the CNES GINS/DYNAMO software. In this presentation the GRGS will present some results derived from the combination of normal equations obtained for the different techniques over two VLBI intensive campaigns referred to as CONT08 and CONT11. |
