TanDEM-X - A New High Resolution Interferometric SAR Mission
TanDEM-X (TerraSAR-X add-on for Digital Elevation Measurement) opens a new era in spaceborne radar remote sensing. The first bistatic SAR mission, is formed by adding a second, almost identical spacecraft, to TerraSAR-X and flying the two satellites in a closely controlled formation with typical distances between 250 and 500 m. Primary mission objective is the generation of a consistent global digital elevation model with an unprecedented accuracy according to the HRTI-3 specifications. Beyond that, TanDEM-X provides a highly reconfigurable platform for the demonstration of new SAR techniques and applications. The mission has been approved for full implementation by the German Space Agency and TanDEM-X is launched on June 21, 2010.

Federal government approves new German space strategy
30 November 2010
The German Federal Government adopted a new space strategy at its cabinet meeting on 30 November 2010. The paper defines the fundamentals of how the high-technology space sector is to develop over the next few years at a national level and in so doing, how it must respond to changing political and societal conditions on the domestic as well as international stages. This strategy is being introduced by the German Federal Ministry of Economics and Technology (Bundesministerium für Wirtschaft und Technologie; BMWi). The strategy paper was drafted jointly with the other federal ministries involved in space activities, and in consultation with scientific and business establishments such as the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR).

22 November 2010
ONLY AVAILABLE IN GERMAN: Thomas Fritz, zuständig für die Prozessierung der TanDEM-X-Daten, zeigt im Blog aktuelle Aufnahmen des Vulkans Merapi: "Als wir vor einigen Wochen die allerersten bistatischen DEM-Aufnahmen mit der TanDEM-X-Formation aufnahmen, war auch der Vulkan Merapi eines der ersten Ziele. Natürlich ahnten wir nicht, dass er kurze Zeit später ausbrechen und diese DEM-Aufnahme bereits zur Unterstützung des Krisen-Managements dienen würde. Mittlerweile gibt es weitere Aufnahmen des Merapi, an denen man den Nutzen der hochaufgelösten und genauen TanDEM-X-DEMs für solchen Krisenfälle erkennen kann."
TanDEM-X-Mission Blog: Baptism of fire for the satellite formation
20 October 2010
Last Thursday, the two German radar satellites of the TanDEM-X formation finally reached their operational orbit configuration, with only a few hundred metres separating them. In this configuration, they act as a unique radar interferometer in space. The next day, on Friday evening, the instruments were switched on, after many careful checks, to acquire the world's first Digital Elevation Model (DEM) data using a free-flying bistatic Synthetic Aperture Radar (SAR) satellite formation. That same night, the jointly acquired data were received and processed by our operational processing chain.
