Twin satellites - TerraSAR-X and TanDEM-X
22 Feb 2023
DLR's TerraSAR-X and TanDEM-X are twin satellites flying in close formation to acquire SAR data of unique geometric accuracy. Operating together, the missions deliver data that are used to generate Digital Elevation Models of Earth.
The satellites are part of the Third Party Missions programme, in which ESA promotes the availability of the data for research and applications development.
