Abstract :
With regard to multistatic configurations such as the Interferometric Cartwheel or the Interferometric Pendulum the need of satellite positioning with a high accuracy is increasing. Not only for baseline estimation but also for image focusing the precise knowledge of the antennas´ absolute and relative positions is essential. This paper suggests a first approach and a possible way of data enhancement based on realistic orbit models
