Improvement of Interior and Exterior Orientation of the Three Line Camera HRSC with a Simultaneous Adjustment

Since January 2004 the High Resolution Stereo Camera (HRSC) on board the ESA Mission Mars Express (MEX) is imaging the surface of planet Mars in color and stereoscopically in high resolution. As part of the entire data processing concept the Institute of Photogrammetry and GeoInformation (IPI) of the Leibniz Universität Hannover and the Department Photogrammetry and Remote Sensing (FPF) of the Technische Universität München are jointly responsible for the photogrammetric adjustment of the MEX-HRSC orientation data. This will be accomplished by registration of the HRSC data to the Mars Observer Laser Altimeter (MOLA) data of Mars Global Surveyor Mission using single strips or neighboring strips forming a block. With the result of the processing chain, high quality products such as Digital Terrain Models (DTMs), ortho-image mosaics and shaded reliefs can be derived from the imagery. In this paper the concept of simultaneous adjustment of interior and exterior orientation and results of photogrammetric point determination is described.
