At the 2015 Paris Air Show, the German Aerospace Center (DLR) presented its Tandem-L concept, which builds on the success of the twin synthetic aperture radar (SAR) satellites Tandem-X, with twin L-band radar satellites tuned to image Earth’s surface to help understand dynamic processes.
The mission would focus on global measurement of forest biomass as well as measure deformations in Earth’s surface at millimeter accuracy to better understand earthquakes, glacier movements, soil-moisture variations and observation of ocean currents.
This next-generation of twin SAR satellites would build on the techniques and technology of Tandem-X, with increased swath width, imaging resolution and improved measurement accuracy.
The mission concept was developed in detail along with NASA/JPL. With planning well underway, the satellites could be launched as early as 2019 if they receive international cooperation.
