Looking for the best-in-class solution for crisis management and innovative commercial business solutions, our Radar Constellation is your best choice.

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

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 very high-resolution 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 to wide area coverage.

Key features

Key advantages of the Radar Constellation are an increased Acquisition Capacity, as well as an improved global mean Revisit Time and a significantly reduced Interferometric Repeat-Cycle supporting data-hungry, high monitoring frequency applications such as e.g.:

  • Change Detection for Image Intelligence as well as Maritime Surveillance, or
  • InSAR Analysis for oil and gas field- or civil engineering structure measurements of ground surface motion (uplift or subsidence) with millimetre precision and high resolution.


  • 6 acquisition modes with lexible spatial resolution (from 25cm to 40m) and footprint
  • Weather and daylight independent site access to any point on Earth
  • High agility (rapid switches between different imaging modes and polarizations)
  • 4/7 days Interferometric Repeat Cycle, Global mean revist time < 24 hrs
  • Unrivalled geometric accuracy and excellent radiometric accuracy
