TerraSAR-X is the first space-mission in Germany to be implemented in a public-private partnership (PPP) scheme

Cooperation Agreement (PPP-contract)DLR EADS Astrium GmbH

Scientific Exploitation via AO process

Mission Control & Ground Segment

Owns all data

Exclusive Commercial Exploitation

Incl. Direct Access Terminal

Satellite built by ASTRIUM

Public-Private Partnership

TerraSAR-X Products

Processing tasks are shared by DLR Germany and Infoterra GmbH

Basic Products (generated by DLR)CEOS L1b data products (Basic products):

SSC: Single Look Slant Range ComplexMGD: Multilook Ground Range Detected GEC: Geocoded Ellipsoid Corrected EEC: Enhanced Ellipsoid Corrected

Value Added Products (generated by Infoterra)

Enhanced Image ProductsOrthorectified image (ORISAR)Mosaic (MCSAR)Oriented Image (OISAR)Ascending / Descending Merge (ADMSAR)

Geo-Information ProductsOrthomap (OMSAR)Change Detection Map (CDMSAR)Subsidence Map (SUBSAR)



Security Considerations

TerraSAR-X data are regarded as highly sensitive due to its high information content

German „data security law“ on its way through the parliament

Satellite commanding and SAR-data is encrypted

Customer authentification and authorization is required„How much time between acquisition and delivery ?“

„Sensitivity check“ for every order

„Who is ordering ?“

„What type of data ?“

„Which target area ?“

License agreement for use of data

HMA Rationale DLR & Infoterra

Coordinated contribution of German National EO missions supplying data to GMES Services

Collaboration with other mission operators - under guidance of ESA - to define and implement interfaces and systems to guarantee seamless data access services (as defined in ESA GSC)

“Heterogeneous Missions Accessibility (HMA) project is the key project to enable interoperable access for query, order and retrieval of mission data

DLR and Infoterra are partner in the HMA project, enabling interoperability with their respective user segments in a harmonized manner (one stop shop)
