Of all 12,000 satellites in orbit, the one with the highest requirement for precise orbit determination is Sentinel-6 MF. Since it is a reference mission for measuring sea level change. Kristin Vielberg has just published an improved force model for S-6 MF: link.springer.com/article/10.1...

Our PhD student Charlotte Hacker (@crc1502-detect.bsky.social @unibonn.bsky.social) published a 40yr record of total water storage anomalies (TWSA), similar to GRACE but from 1984 on. She combined SLR, DORIS and climate data in a new method. zenodo.org/records/1582... doi.org/10.22541/ess...

We have a new doctor. Congrats to Armin Corbin for defending his PhD work on numerical simulation of mass density in the upper Earth's atmosphere with data assimilation at @unibonn.bsky.social (bonndoc.ulb.uni-bonn.de/xmlui/handle...).
