Improved estimation of ocean tide loading displacements using multi-GNSS kinematic and static precise point positioning
Multi-GNSS solutions are typically considered to improve GPS-only ocean tide loading (OTL) displacements, as they effectively mitigate the constraints imposed by the single-system GPS orbital configuration on ...

Regional Geoid Undulations from CHAMP, Represented by Locally Supported Basis Functions
Regional geoid undulations are determined from CHAMP data using various locally supported basis functions to assess their respective efficiency, accuracy and multi-resolution representation properties. These f...

CHAMP Gravity Field Solutions and Geophysical Constraint Studies
We report results on the use of CHAMP observations for Earth's mean and time-varying gravity field solutions and the associated geophysical interpretation. 1.5 years of CHAMP data from May 2001 through Februar...

Recovery of Isostatic Topography over North America from Topographic and CHAMP Gravity Correlations
We investigate North American crustal structure and mass loads from spectral correlation analysis of topographic, CHAMP and terrestrial gravity data. We use free-air and terrain gravity correlations to isolate...

CHAMP Gravity Anomalies over Antarctica
Before CHAMP, the Antarctic gravity field was constrained predominantly by satellite altimetry-derived gravity measurements over the oceans and the variations in satellite orbits at altitudes of about 700 km a...
