TerraSAR-X Mission

TerraSAR-XLaunched 15th June 2007from Baikonur with Dnepr-15 years nominal lifetimePublic-Private Partnership between German Ministry of Education and Science (BMBF) and EADS AstriumOperations by DLR (satellite, ground segment)Exploitation by DLR (science) and Infoterra GmbH (commercial)

TerraSAR-X – Characteristics

Operation “cloudfree” and 24/7timely coverage (season, reference year)rapid coverage / access (daylight independent)

Variable imaging modes: offering targeted information for a multitude of purposes:

very high spatial resolution (up to 1 m): detailed information acquisitionvery high temporal resolution (up to 2.5 d): reliable detection of changeshigh spatial coverage (up to 100km x 1500 km): monitoring of huge areaspolarization modes (VV, HH, VH, HV): multiple information sources

allowing object separation with high accuracy

Three image acquisition modes:ScanSAR > 18 mStripMap > 3.5 mSpotLight > 1 m


ScanSAR: 100x150 qkmStripMap: 30x50 qkm

TerraSAR-X Imaging Modes

SpotLight: 5x10 qkm

TerraSAR-X enables effective and efficient resource monitoring and management

Large area coverage to- improve management of resources- monitor and fight deforestation and desertification- identify drinking water pollution sourcesHigh temporal resolution to- raise agricultural productivity and provide timely food aid- increase understanding of climate change and its impact onenvironment and biodiversity

High spatial resolution to- support sustainable urban planning for mega-cities- provide timely information for disaster and crisis response actions

TerraSAR-X provides up-to-date information forrapid mapping and site monitoring
