TerraSAR-X TanDEM-x


TerraSAR-X and TanDEM-X dependably acquire high-resolution and wide-area radar images independent of the weather conditions. The two satellites feature a unique geometric accuracy that is unmatched by any other spaceborne sensor. With the upcoming addition of PAZ, the three almost identical satellites will be operated in a constellation and will deliver optimized revisit time, increased coverage and improved service.

  • – Wavelength 3,1 cm
  • – Altitude 514 km
  • – Independence from weather conditions
  • – Cycle 11 days
  • – The maximum measurement frequency (Revisit) – 43 h.
  • – Launch periods: TerraSAR-X: June 2007, TanDEM-X: June 2010
