TerraSAR X


Designation 31698 / 07026A
Launch date 15 Jun 2007
Country of origin Germany
Mission Remote sensing
Perigee/Apogee 514 km
Launch vehicle Dnepr #9

Should cost EUR 130 million (including launch). DLR provides EUR 102 million while Astrium brings in EUR 28 million.

DLR is be responsible for scientific use while exclusive commercial marketing of the data will be carried out by Infoterra GmbH (Friedrichshafen, Germany), a wholly-owned subsidiary of Astrium.

The construction of a partner satellite called TanDEM-X is planned, which would operate alongside TerraSAR-X as of 2009. The pair would create a digital elevation model of the entire planet with an unprecedented degree of resolution.

After 2 years, the satellite took approximately 35,000 radar images of the Earth's surface.

Technical data


Prime contractor Astrium
Platform AstroBus (mixes LeoStar and FlexBus)
Mass at launch 1346 kg
Mass in orbit  
Solar array  
DC power  
Design lifetime 5 years

Will provide upto 1-m resolution images with its X-band SAR. The beam can be angled within a slewing range of 20 to 60 degrees by selectively superimposing multiple individual radar beams.
3 different levels of resolution (16 m, 3 m and 1 m) and image size can be chosen.

Secondary payloads:
LCT: Laser Communication Terminal: an optical data communication experiment, built by TESAT, to downlink data to an earth station at high throughput. Working perfectly after 2 years.

TOR: Tracking, Occultation and Ranging experiment: 2 GPS receivers to perform fine (10 cm) orbit corrections.
