The German radar satellite TerraSAR-X will orbit the Earth in a polar orbit at a height of 514 kilometres; using the mission's newly designed active antenna, it will gather high-quality X-band radar data from the entire planet. TerraSAR-X will operate independent of weather conditions, cloud coverage or lighting and will supply radar data at a resolution of up to 1 metre.
