Zusammenfassung:
FAMOS (Finalizing Surveys for the Baltic Motorways of the Sea) is a recently run project which was supported by EU to improve the safety of ship navigation on the Baltic Sea. One task of FAMOS was to work on a common height reference for the Baltic Sea, the Baltic Sea Chart Datum 2000 (BSCD2000), which will be based on a new gravimetric geoid for this sea. The German institutions German Research Centre for Geosciences (GFZ), Federal Agency for Cartography and Geodesy (BKG), Federal Maritime and Hydrographic Agency (BSH) and Technical University of Darmstadt performed several marine gravimetry surveys to contribute to this project. The primary measurement equipment was GFZ’s Chekan-AM gravimeter. On two of these campaigns an iMAR strapdown inertial measurement unit (IMU) was used together with the Chekan. The data records from both instruments are of very good consistency.
Since the FAMOS project ended ahead of the planned schedule already in 2019, finalization of the new chart Datum is now coordinated by the Chart Datum Working Group within the Baltic Sea Hydrographic Commission. It is planned to implement the new BSCD2000 by 2023.
