TerraSAR-X



TerraSAR-X reliably acquires high-resolution and wide-area radar images, independent of the weather conditions. The satellite features a unique geometric accuracy that is unmatched by any other commercial spaceborne sensor.


TerraSAR-X is specifically optimised to meet the requirements of commercial users around the globe who require readily available, high-quality and precise Earth observation data.



TerraSAR-X benefits:


  • · Flexible coverage and resolution: high resolution for specific target areas, medium resolution for large area coverage
  • · Excellent geometric and radiometric accuracy
  • · Comprehensive network of ground stations and Direct Access Services ensure data delivery in near real time



The identical Spanish satellite PAZ (owner and operator: Hisdesat) will be launched into the same orbit as TerraSAR-X in 2015. Together, the satellites form a constellation with significantly optimised coverage and capacity. The new constellation supports numerous data-intensive and time-critical applications in the areas of crisis management, defence and security.


Together with its almost identical twin TanDEM-X, TerraSAR-X acquires the data basis for the WorldDEM™, a global Digital Elevation Model with unrivalled quality, accuracy and coverage.


With a scene size of up to 405,000km² the new Wide ScanSAR mode has been specifically optimised for maritime monitoring applications. Wide ScanSAR data enables continuous large-area surveillance of shipping traffic, monitoring of sea ice and timely detection of oil spills.


The new Staring SpotLight mode is now available for applications requiring highly detailed object information. With a resolution of down to 0.25m, improved radiometric quality and outstanding geometric sensor accuracy, Staring SpotLight data provides precise information for image intelligence (IMINT) and GEOINT applications.


ST Electronics (Satcom & Sensor Systems) is the authorised reseller of TerraSAR-X and TanDEM-X images in Singapore.
