TanDEM-X – a Valuable Partner for TerraSAR-X

TanDEM-X (TerraSAR-X add-on for Digital Elevation Measurements) is a second, very similar spacecraft that will orbit in a close formation flight with TerraSAR-X, scheduled to be launched in 2009.

This unique twin satellite constellation will allow the generation of global digital elevation models (DEMs) at an unprecedented accuracy, coverage and quality – a consistent DEM of the Earth’s land surface is envisaged to be acquired and generated within three years after launch.

The mission has been agreed as a new Public Private Partnership between Astrium GmbH and DLR. Again, Infoterra GmbH will be responsible for commercially marketing the data.
