Successfully launched on June 15th, 2007, TerraSAR-X has been fully operational since early 2008. With its active antenna, the spacecraft acquires high-quality X-band radar images of the entire planet whilst circling Earth in a polar orbit at 514 km altitude. TerraSAR-X is designed to carry out its task for 5.5 years, independent of weather conditions and illumination, and reliably provides radar imagery with a resolution of up to 1m and a unique geometric accuracy.
Key Technical Features include:
- Active phased array X-band SAR
- Single, dual and quad polarisation
- Side-looking acquisition geometry
- Sun-synchronous dawn-dusk repeat orbit
- Repetition rate: 11 days; due to swath overlay, a 2.5 day revisit time (2 days at 95% probability) to any point on Earth can be achieved
- Orbit altitude range from 512 km to 530 km
