The operation of two SAR satellites flying in close formation enables bistatic operation allowing for highly accurate single-pass interferometry. TanDEM-X has been operationally demonstrating this novel technique since 2010. With a typical separation between the TerraSAR-X and TanDEM-X satellites of 120 to 500 m a global DEM with 1 m height accuracy at 12 m posting has been generated. Final DEMs are of consistent homogeneous quality and well within specifications. Tandem-L, a proposal for an innovative L-band SAR mission, is also employing bistatic interferometry aiming at the systematic observation of dynamic processes on the Earth{'}s surface. Thanks to the novel imaging techniques and the vast recording capacity of up to 8 Terabytes/day, it will provide vital information for solving pressing scientific questions in the biosphere, geosphere, cryosphere, and hydrosphere and will make an essential contribution for a better understanding of the Earth system and its dynamics.
