After obtaining an aerospace engineering degree from the Technical University of Dresden, Ralph Kahle conducted research as a doctoral student at the DLR Institute of Planetary Research in Berlin on the areas of exposure to near-Earth asteroids and comets, as well as the avoidance of collisions.
Since 2004, he has been a researcher at the German Space Operations Center (GSOC) at DLR Oberpfaffenhofen. He works on flight dynamics systems for satellite missions for communications and Earth observation as well as robotic missions such as the on-orbit servicing mission DEOS.
Ralph Kahle is the flight dynamics engineer for the TerraSAR-X / TanDEM-X Mission. His responsibilities include precise orbit and attitude determination for the satellites, measuring their position relative to one another with millimetric accuracy, the generation of auxiliary products for radar processing, and control of the satellite formation.
