The research of the working group Astronomical, Physical and Mathematical Geodesy (APMG) is focused on the following topics

• satellite geodesy and the Earth’s gravity field (concerning current satellite missions such as GRACE and Swarm as well as simulation studies for future missions)

• geodetic Earth system research (improving the understanding of processes in ocean, hydro- and atmosphere and solid Earth, by combining space observations such as satellite gravimetry or –accelerometry, radar altimetry or GNSS with numerical models)

• geodetic methods (for example the development of efficient inversion or data integration algorithms)

To this end, we collaborate with several national and international partners and institutions.
