I'm proud having joined the course of the IDS as head of GFZ's AAC and having met so many old and new friends and colleagues. Heading of our AAC is overtaken by my colleague Patrick Schreiner in future. He meanwhile became quite experienced in precise orbit and parameter determination, not only but also from DORIS observations. Our department director Prof. Harald Schuh and our section head Prof. Frank Flechtner are very much in favor of these activities and will certainly have an open ear in any issues concerning the continuation of our collaboration. Let me say that it was a honor to work with you over those many years now, with my french friends even over decades reaching back to the GRIM gravity field era. Merry Christmas and a happy new year Rolf -- -------------------------------------------- Dr. Rolf Koenig Dep. 1: Geodesy Phone: +49 (0)8153/90832-14 FAX: +49 (0)8153/90832-01 Email: rolf.koenig@gfz-potsdam.de --------------------------------- Helmholtz Centre Potsdam GFZ German Research Centre for Geosciences Claude-Dornier-Str. 1, 82234 Wessling -------------------------------------------- Please do not reply directly to this message, but send comments and suggestions to IDS.central.bureau@cls.fr
