Present state of GGOS D-A-CH• GGOS D-A-CH was approved as GGOS Affiliate on 19 May 2021 (Chair: H. Kutterer)• Basis and forum for GGOS-related activities in the D-A-CH region; stimulator and incubator for
GGOS-related coordinated research• Call for Participation in 2021: 19 expressions of interest from all three countries•

Universities in Berlin, Bern, Bonn, Dresden, Hannover, Karlsruhe, Munich, Stuttgart, Vienna, Zurich•

Research institutions and national agencies: BKG, BEV, GFZ• Organization of a DFG Roundtable on 19-20 May 2022 in Munich: Discussion of a coordinatedresearch proposal to advance GGOS
• Good exchange and cooperation with GGOS Japan  Presentation of GGOS D-A-CH at GGOS
Japan meeting on 17 March 2022, planned joint proposal, stay of a KIT Master student at GSI
Japan• Regular reporting to GGOS CB and to national geodetic commissions (joint annual meeting in2022 in Innsbruck, Austria, 19-22 September 2022)• Participation in GGOS Days (14-15 November 2022 in Munich)2White Paper „Geodesy 2030“

Subject and methodology
Integrated determination of geodetic parameters and products according to GGOS
• Consistent combination of geometry (in terms of volume) and gravity (in terms of mass)
including temporal variations• Effective combination of the different levels of the GGOS observation architecture (inparticular MEO+LEO)• Optimization of the observing system including digital simulation (based on PLATO)• Innovative technologies and future geodetic observation infrastructure• Monitoring of the spatial geodetic reference frames (geometry, gravity) in near real time
• Interface to other disciplines
