Gravity Field Analysis from the Satellite Missions CHAMP and GOCE
This work describes global gravity field modeling from observations of the CHAMP and the GOCE satellite mission. In the case of CHAMP the so-called Energy Balance Approach is applied to measurements of GPS high-low tracking of the low orbiting CHAMP spacecraft. In the case of GOCE gravity gradiometry is the main observable. The experience gained processing real data of the CHAMP satellite missi...
متن کاملCombining CHAMP and Swarm Satellite Data to Invert the Lithospheric Magnetic Field in the Tibetan Plateau
CHAMP and Swarm satellite magnetic data are combined to establish the lithospheric magnetic field over the Tibetan Plateau at satellite altitude by using zonal revised spherical cap harmonic analysis (R-SCHA). These data are integrated with geological structures data to analyze the relationship between magnetic anomaly signals and large-scale geological tectonic over the Tibetan Plateau and to ...
متن کاملStudies of Geomagnetic Pulsations Using Magnetometer Data from the CHAMP Low-Earth-Orbit Satellite and Ground-Based Stations: a Review
We review research on geomagnetic pulsations carried out using magnetic field measurements from the CHAMP lowEarth-orbit (LEO) satellite and ground-based stations in South Africa and Hungary. The high quality magnetic field measurements from CHAMP made it possible to extract and clearly resolve Pi2 and Pc3 pulsations in LEO satellite data. Our analyses for nighttime Pi2 pulsations are indicativ...
متن کامل‘DEOS CHAMP-01C 70’: a model of the Earth’s gravity field computed from accelerations of the CHAMP satellite
Performance of a recently proposed technique for gravity field modeling has been assessed with data from the CHAMP satellite. The modeling technique is a variant of the acceleration approach. It makes use of the satellite accelerations that are derived from the kinematic orbit with the 3-point numerical differentiation scheme. A 322-day data set with 30-s sampling has been used. Based on this, ...
متن کاملField-aligned current associated with low-latitude plasma blobs as observed by the CHAMP satellite
Here we give two examples of low-latitude plasma blobs accompanied by linearly polarized perpendicular magnetic deflections which imply that associated field-aligned currents (FACs) have a 2-D sheet structure located at the blob walls. The estimated FAC density is of the order of 0.1 μA/m2. The direction of magnetic deflections points westward of the magnetic meridian and there is a linear corr...
