TanDEM-X
Sign in to saveTanDEM-X (TerraSAR-X add-on for Digital Elevation Measurement) is a German twin satellite mission using interferometric synthetic aperture radar (InSAR). It is developed in a public-private partnership between the German Aerospace centre (DLR) and EADS Astrium (now Airbus Defence and Space). It consists of the original TerraSAR-X satellite (TSX) and an identical spacecraft (TDX) in formation flying, with typical distances between 250 and 500 m. The two satellite constellation allowed the generation of the WorldDEM global digital elevation models starting in 2014.

==WorldDEM== The primary mission objective is the generation of WorldDEM, a consistent global Digital Elevation Model (DEM) with an unprecedented accuracy better than DTED Level 2 specifications. WorldDEM resolution will correspond to DTED Level 3 (post spacing of better than 12 meters) and a height accuracy of better than 2m (relative)- a standard not yet defined. Digital Elevation Models of posting better than DTED Level 2 are often called HRTI (High Resolution Terrain Information) DEM.
