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)
