Since the launch of TerraSAR-X on June 15, 2007, the required precise orbit products have been provided by the German Space Operations Center (DLR/GSOC) to support operational space-borne Synthetic Aperture Radar (SAR) and interferometric SAR (InSAR) image processing. The TerraSARX precise trajectory is reconstructed solely based on the Global Positioning Systems (GPS) measurements from a geodetic grade dual-frequency Integrated Geodetic and Occultation Receiver (IGOR) onboard the spacecraft. The GPS-based precise orbit determination (POD) strategy used in the estimation of the precise TerraSAR-X orbit and its performance will be fully described in this paper. A 5-month statistics from the internal and external orbit assessment indicate a root-mean-squared (RMS) 3D orbit accuracy of better than 10 cm and 20 cm for the precise science orbit (PSO) and precise rapid orbit (PRO) products respectively. The POD performance of the backup single frequency MosaicGNSS receiver to support operational PRO product generation in case of IGOR tracking failure or interruptions is described as well.
