This thesis addresses the problem of planning data takes possibilities for different target areas. These data takes are done by SAR satellites and will be developed to a digital elevation model by an interferometric process. SAR stands for synthetic aperture radar. The used satellites can be part of a satellite constellation. This satellite constellation can consist of different or identical assets. It is important that the sensors installed on the satellites are compatible in interferometric manner. The special feature which must be provided for the interferometric data takes is that the satellite must have a defined geometric position in space. Therefor a baseline is defined, a distance between the position of the involved satellites. This baseline cannot exceed an inherent limit. This creates two challenges. One is to find the limits for the baseline in heterogeneous systems the other is the propagation of the satellite orbits due to perturbations. There are existing satellite constellations, which are used for interferometric purposes like e.g. COSMO-SkyMed and TanDEM-X. Those satellite systems have typically a repeat path orbit to obtain the interferometric data takes. COSMOSkyMed uses four satellites placed on an orbit plane to obtain interferometric data takes within a period less than the repeat path orbit interval. These manifold satellite systems open the opportunity to create data takes in an overlapping system. This thesis describes a planning method to predict data take opportunities in SAR satellite systems to create interferometric products and describes all necessary basics.
