Vermessung des Erdschwerefelds mit Satelliten: Genauigkeitssteigerung durch Einsatz neuer Techniken

Christoph Foerste
The Earth’s gravity field is inhomogeneous and temporally variable. It reflects the inner and outer structure of our planet. Therefore, the investigation of the gravity field is essential for understanding the System Earth. But the precise mapping of the gravity field on global scales including its temporal variations is only possible using satellites. This can be done indirectly by analyzing satellite orbit deviations which began in 1957 with the estimation of the Earth’s flattening by...
