TerraSAR-X / TanDEM-X
TerraSAR-X and TanDEM-X dependably acquire high-resolution and wide-area radar images independent of the weather conditions. The two satellites feature a unique geometric accuracy that is unmatched by any other spaceborne sensor.
Both satellites are almost identical and operate in six alternate operating modes for a wide range of applications in Earth observation: Ranging from Staring SpotLight mode with a resolution of up to 25 cm at a scene size of e.g. ~ 4 km x 3.7 km mainly for image intelligence applications to Wide ScanSAR providing a resolution of 40 m at a scene size of 270 km × 200 km (extendable to a scene length of 1,500 km) particularly suitable for maritime applications. Other applications include highly precise change detection and monitoring applications, support of intelligence and security mission, disaster response and as well as mapping and generation of digital elevation models using interferometry and radargrammetry. Thanks to different polarimetric combinations (single or dual polarisation and even full Polarimetric) and processing levels the delivered imagery can be tailored specifically to meet the requirements of the application.

Designed to return unique images of the Earth for five years, the German radar satellite TerraSAR-X has outdone itself. The satellite has been in operation for twice that time - and there is still no end in sight to its service.
Since the launch of the first Earth-observing satellites in the 1970s, numerous missions from international space organisations have taken to the sky. Today, decades of data are helping scientists to build a better picture of changes to our planet.
