Abstract The Earth Orientation Center of the IERS, located at Paris Observatory, SYRTE, has
the task to provide to the scientific community the international reference time series for the …

We used a wavelet formulation of the classical spectral isostatic analysis to invert satellite-
derived gravity and topography/bathymetry for elastic thickness (Te) over South America and …

Most satellites in a low-Earth orbit (LEO) with demanding requirements on precise orbit
determination (POD) are equipped with on-board receivers to collect the observations from …

In dieser Arbeit werden verschiedene Modellansätze für die Auswertung von SST-
Beobachtungen zur Gravitationsfeldbestimmung vorgestellt, die besonders auf …

The two GRACE satellites provide the ideal platform to study the performance of different
strategies for precise orbit determination using undifferenced or doubly differenced GPS …

This article provides a survey on modern methods of regional gravity field modeling on the
sphere. Starting with the classical theory of spherical harmonics, we outline the transition …

We propose a methodology for local gravity field modelling from gravity data using spherical
radial basis functions. The methodology comprises two steps: in step 1, gravity data (gravity …

We present a new map of the spatial variations in effective elastic thickness, Te, along the
Andes estimated using Bouguer coherence. The Te variations reflect interactions between …

Radar altimetry was, very early in the development of space technology, identified as a key
technique to provide essential information on solid Earth and ocean dynamics. Satellite …

Antarctica is the only continent that suffers major gaps in terrestrial gravity data coverage. To
overcome this problem and to close these gaps as well as to densify the global satellite …
