Formation swapping - Comic about the TanDEM-X mission

30.07.2013 | posted by Ralph Kahle

An exciting manoeuvre awaits us. In early August (6–8 August 2013), the two TanDEM-X mission satellites will be reversing their formation. Until now, the TanDEM-X satellite has been circling around its twin, TerraSAR-X, in an anti-clockwise direction; after the reversal, it will circle clockwise. This complicated change to the formation in which they have been flying for almost three years is necessary to observe regions that are difficult to image, such as mountain ranges, from the opposite viewing angle. This blog entry takes an unconventional look at the planned change in formation ... read more

The final stage in the construction of the German-Indonesian tsunami early warning system

31.03.2011 | posted by Stefan Dech

On 26 December 2004, a devastating tsunami destroyed large parts of the coastline of the Indian Ocean. It is estimated that 250,000 people lost their lives because there was no early warning system. Shortly afterwards, the German government decided to spend 50 million Euros to develop a tsunami early warning system in Indonesia, the most severely affected country. Scientists from major German research centres presented innovative concepts for such a system to the political decision makers. Convinced of the feasibility of the proposal, the German Federal Ministry of Education and Research (Bundesministerium für Bildung und Forschung; BMBF) decided to support the project, now named the German-Indonesian Tsunami Early Warning System (GITEWS), as a joint development led by the German Research Centre for Geosciences (Deutsches GeoForschungsZentrum; GFZ) in Potsdam. read more
