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.

2007年6月15日 · TerraSAR-X and TanDEM-X are German radar satellites from DLR (the German Aerospace Center). TerraSAR-X launched in 2007 and was joined by TanDEM-X in 2010. Both satellites remain operational. The twin satellites feature a unique geometric accuracy that is unmatched by any other spaceborne sensor.

The goal of the TerraSAR-X add-on for Digital Elevation Measurement (TanDEM-X) mission is to generate a high-accuracy global Digital Elevation Model (DEM). The goal will be achieved through a second SAR satellite (TanDEM-X) flying in a tandem orbit configuration with TerraSAR-X.

2024年9月2日 · TanDEM-X is an interferometric SAR satellite mission, funded in a public/private collaboration between the German Aerospace Centre (DLR) and Airbus Defence and Space (formerly EADS Astrium GmbH). The satellite launched in June, 2010 and constructs three-dimensional images of Earth’s surface.

2010年6月21日 · The TanDEM-X satellite is a replica of TerraSAR-X with minor extensions. It has an additional cold gas propulsion system and can therefore fine-tune its orbit for formation flight with TerraSAR-X. TanDEM-X also receives attitude and position data from its twin satellite.

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.

Abstract: TanDEM-X (TerraSAR-X add-on for Digital Elevation Measurements) is an innovative formation flying radar mission that opens a new era in spaceborne radar remote sensing.

TanDEM-X (TerraSAR-X add-on for Digital Elevation Measurements) is an Earth observation radar mission that consists of a SAR interferometer built by two almost identical satellites flying in close formation. With a typical separation between the satellites of 120m to 500m a global Digital Elevation Model (DEM) has been generated.

The TerraSAR-X science objectives are to make multi-mode and high-resolution X-band radar data available for a wide spectrum of scientific applications in such fields as hydrology, geology, climatology, oceanography, environmental monitoring, …

2010年6月21日 · The TanDEM-X project is being implemented by a Public-Private Partnership (PPP) between the German Aerospace Center (DLR) and Astrium GmbH. The primary goal of the TanDEM-X (TerraSAR-X add-on for Digital Elevation Measurement) mission is to generate a global digital elevation model.

Since August 2016 the 12 m and 30 m global TanDEM-X Digital Elevation Model is available for scientific users. In addition in October 2018 the open call for the 90 m global TanDEM-X DEM was launched with a fast access to the data.

TanDEM-X (englisch TerraSAR-X-Add-on for Digital Elevation Measurements, deutsch „TerraSAR-X-Erweiterung für digitale Höhenmessungen“) ist ein deutscher Radarsatellit, der gemeinsam mit dem Satelliten TerraSAR-X mittels SAR im X-Band die Erdoberfläche stereographisch vermisst. [1] Daraus entsteht ein weltweites Geländemodell mit einer …
