Product nodeOverviewThe German radar satellite TerraSAR-X was successfully launched on June 15th, 2007, from Baikonur in Kazakhstan. With its active antenna, the spacecraft acquires new 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 five years, independent of weather conditions and illumination, and reliably provides radar images with a resolution of up to 1m. 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 can be achieved Orbit altitude range from 512 km to 530 km Three operational imaging modes: - SpotLight: up to 1m resolution, 10 km (width) x 5 km (length) - StripMap: up to 3m resolution, 30 km (width) x 50 km (length) - ScanSAR: up to 18 m resolution, 100 km (width) x 150 km (length)
