Radar Constellation (TerraSAR-X / PAZ)

Inquiry Form

Radar Satellite services of unique precision, quality, and reliability.

Categories: . .

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

  • 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
