TanDEM-X (TerraSAR-X add-on for Digital Elevation Measurement) is the name of TerraSAR-X's twin satellite, a German Earth observation satellite using SAR (Synthetic Aperture Radar) - a modern radar imaging technology. Implemented in a Public-Private-Partnership between the German Aerospace centre (DLR) and EADS Astrium (now Airbus Defence and Space), it is a second, almost identical spacecraft to TerraSAR-X (TSX). TanDEM-X (TDX) is also the name of the satellite mission flying the two satellites in a closely controlled formation with typical distances between 250 and 500 m.[1] The twin satellite constellation allowed the generation of WorldDEM global digital elevation models starting in 2014.
