The course deals with modern techniques for the determination of global and regional gravity field models. For the global
gravity field determination both the integration and the least squares methods are discussed and their performances are
compared. In the regional case the remove-restore technique and its implementation by FFT techniques is extensively
studied.
Prerequisites: Modeling and Data Analysis in the Field of Physical Geodesy
The course consists of two parts: The orbit determination and the orbit analysis. Orbit determination aims at the
computation of a dense time series of orbital positions, which are consistent with observations of ranges and range rates
between an observer and the satellite. After having presented numerical integration methods and variational equations as
theoretical background the dynamic and the reduced-dynamics method of orbit computation are presented. The orbit analysis
is based either on the Lagrangian disturbing equations or Hills equations of satellite motion. Both methods are presented
and compared. Numerical problems occurring due to coefficient lumping are discussed.
