TerraSAR-X Radar Satellite Imagery

Radar Satellite Services of Unique Precision, Quality, and Reliability
TerraSAR-X Blockname

The high-resolution radar satellite TerraSAR-X reliably provides high-resolution SAR imagery with a resolution down to 25cm independent of weather conditions and illumination.
The satellite features a unique geometric accuracy unrivalled by any other commercial spaceborne sensor today and an excellent radiometric accuracy.

Most Accurate High-Resolution Radar Satellite in Orbit

TerraSAR-X Data in GeoStore

Airbus Defence and Space offers an extensive portfolio of high-quality TerraSAR-X data products of different modes or processing levels depending on the intended utilisation. TerraSAR-X was specifically designed to meet the requirements of commercial users around the globe and is optimised to deliver data for a wide range of sophisticated applications.

These radar image products are specified in accordance with the individual needs and application requirements of each customer prior to their acquisition. The basic imagery products can subsequently be enhanced in order to secure an optimised applicability.

TerraSAR-X Key Features

  • Flexible resolution (0.25m / 1m / 3m / 18.5m / 40m) and footprint: high resolution for specific target areas, medium resolution for large area coverage
  • Geometric accuracy unrivalled by any other commercial spaceborne sensor today
  • Excellent radiometric accuracy
  • Weather-independent site access time of 2.5 days max. (2 days at 95% probability) to any point on Earth
  • Unique agility (rapid switches between imaging modes and polarisations)

The unique design of TerraSAR-X's SAR antenna enables a variety of polarimetric combinations: single or dual polarisation and even full polarimetric data takes are possible. Different processing levels are optionally selectable for each image ranging from Level 1B data (with full phase information) to orthorectified imagery.


Further refined products, like mosaics or image merges from ascending and descending orbits, are available.

TerraSAR-X Mission

TerraSAR-X is the first German radar satellite built in a Public Private Partnership (PPP) between the German Aerospace Centre (DLR) and Europe’s leading satellite system specialist EADS Astrium GmbH. The commercial marketing of TerraSAR-X data and services is conducted by Infoterra GmbH, the German part of Airbus Defence and Space, exclusively.

Scientific exploitation, mission planning and operation of the satellite is the responsibility of DLR. The scientific use of TerraSAR-X data is coordinated via DLR's TerraSAR-X Science Service System.
