TerraSAR-X and TanDEM-X Mission Status

Inhalt:
TerraSAR-X, launched on June 15th 2007 and its identically constructed twin satellite TanDEM-X, launched on June 21st 2010, supply high-quality radar data in order to serve two mission goals: Scientific observation of the Earth and provision of remote sensing data for the commercial market (TerraSAR-X mission) and the generation of a global digital elevation model (DEM) of the Earth’s surface (TanDEM-X mission). The status of both, the strategic orientation of the TerraSAR-X and TanDEM-X mission, especially with a view to the envisaged generation of a global a three-dimensional change map, called “Change DEM” as well as the status of the space and ground segment activities will be presented in this paper.
