Radar Constellation | TerraSAR-X/TanDEM-X and PAZ

Unique Precision, Quality and Reliability

Our Radar Constellation reliably acquires the widest range of radar satellite images, from the highest resolution to wide area coverage - regardless of weather and daylight conditions.

Radar image acquisition in a unique constellation

Radar constellation - Six versatile imaging modes


What is the Radar Constellation?

Radar image acquisition in a unique constellation.

The German TerraSAR-X / TanDEM-X satellite formation and the Spanish PAZ satellite (managed by Hisdesat Servicios Estratégicos S.A.) are being operated in the same orbit tube and feature identical ground swaths and imaging modes - allowing Airbus and Hisdesat to establish a unique commercial Radar Constellation. The satellites carry a high frequency X-band Synthetic Aperture Radar (SAR) sensor in order to acquire datasets ranging from very high-resolution imagery to wide area coverage.


  • Radar Constellation 'toolbox': Imagery in 6 different imaging modes with a flexible spatial resolution (from 25cm to 40m) and area coverage (footprint)
  • Weather and daylight independent site access to any point on Earth
  • High agility (rapid switches between different imaging modes and polarisations)
  • 4/7 days interferometric repeat cycle, global mean revist time < 24 hrs
  • Unrivalled geometric accuracy and excellent radiometric accuracy
Did you know?

Our Radar Constellation provides you with reliable access to highly accurate Earth observation data in near real-time, independent of weather and daylight conditions.

Your advantages with the Radar Constellation

Our Radar Constellation 'toolbox' supports a variety of applications

Reliable and timely

Fully operational at night or during periods of cloud coverage

Versatile and flexible

Wide area monitoring, suited for e.g. Maritime surveillance, or pinpoint detail down to 25cm resolution, allows for interpretation close to optical imagery

Exact and precise

Very high-resolution (VHR) SAR data with unrivalled geometric accuracy and excellent radiometric accuracy

Constellation capabilities

Increased acquisition capacity, improved global mean revisit time and a significantly reduced interferometric repeat-cycle supporting data-hungry, high monitoring frequency applications
