Earthquake Signatures in the Ionosphere Deduced from Ground and Space Based GPS Measurements plasma density by atmospheric-ionospheric coupling processes. Because of their sensitivity to the ionospheric ionization, ground and space based GPS measurements offer a unique opportunity for detecting earthquake signatures in the ionosphere. Although numerous case studies and statistical analyzesApogee 发表于 2025-3-23 15:20:32
Global Atmospheric Sounding with GPS Radio Occultation aboard CHAMPare analyzed by an operational satellite orbit and occultation processing system at GFZ. In total, more than 200,000 precise globally distributed vertical profiles of refractivity, temperature and water vapor are provided as of June 2005. The operational ground infrastructure from GFZ allows for theComprise 发表于 2025-3-23 20:58:59

Static and Time-Variable Gravity from GRACE Mission Datay the GRACE Science Data System teams. In general, the spatial resolution of the field from pre-CHAMP satellite only models of about 1000 km can be increased by a factor of 5 – 6 thanks to the micrometer-precise K-band intersatellite link. The currently obtained gain in accuracy reaches one to two oPalatial 发表于 2025-3-24 12:23:00
Gravity Field Recovery from GRACE-SST Data of Short Arcsn the space domain depending on the roughness of the gravity field features. On the one hand, the maximum degree of the spherical harmonic expansion has to be selected as high as possible to bring out the maximum of gravity field information out of the data. On the other hand, an increasing maximalExpand 发表于 2025-3-24 18:05:53

High Frequency Temporal Earth Gravity Variations Detected by GRACE Satellitesatmospheric and oceanic motions. Exploitation of precise GRACE satellite-to-satellite ranging measurements now makes it possible to monitor these changes on a global scale with a moderate spatial resolution. Thus, a time series of daily 10 × 10 Earth gravity models has been produced for the time spa脱水 发表于 2025-3-24 23:18:26
From Kinematic Orbit Determination to Derivation of Satellite Velocity and Gravity Fieldrelations between kinematic POD and gravity field determination. We discuss determination of kinematic velocities out of kinematic positions that enter the gravity field determination in the form of kinetic orbital energy. After testing several numerical differentiation techniques, we selected conce
