DLR IPY Data Portfolio: Terra. SAR-X High Resolution SAR Data from Space Erhard Diedrich Head of Division International Ground Segment DLR – German Remote Sensing Data Center
Introduction High-resolution radar mission National Implementation Launch: June 15 th, 2007 Scientific and commercial applications Public / private co-funding Ø Public Private Partnership (PPP) Folie 2 Institut für Methodik der Fernerkundung bzw. Deutsches Fernerkundungsdatenzentrum
“Terra. SAR-X, a National Science Mission with Commercial Potential” Public Private Partnership DLR • Project Management • G/S Development & Ops • Science Coordination • System Engineering Support EADS Astrium • Platform Development • Instrument Development • Launch on Dnepr-1 Infoterra • Service Infrastructure • Information Products • Commercial Exploitation Main Mission Goals: · Provision of Terra. SAR-X data and products for scientific applications public interest · Commercial exploitation of remote sensing data by industry Folie 3 Institut für Methodik der Fernerkundung bzw.

Terra. SAR-X Satellite -514 km altitude -11 days orbit repeat cycle -Right looking, but rolling to left looking possible -256 Gbit memory (~350 secs Strip. Map data) -Average load case: 110 secs in Strip. Map and 50 secs in Spotlight mode -Peak load (x 2) -Transmit & receive in H or V polarization (single / dual) -Experimental dual receive antenna mode Folie 4 Institut für Methodik der Fernerkundung bzw.

Access to Terra. SAR-X data Mission data policy basics Commercial exploitation: Infoterra / EADS-Astrium Scientific utilization: DLR Both parties equally share the satellite resources Infoterra Commercial order service and customer support Catalogue and future products Direct Access service and value added products DLR Science coordination Management of data access via scientific proposals (like Cat 1 use of ESA) Catalogue and future products Folie 10 Institut für Methodik der Fernerkundung bzw. Deutsches Fernerkundungsdatenzentrum
Access to Terra. SAR-X data for scientific use I The status is gained via a selection process proposal submission evaluation (mission objectives, data requirements, scientific use criteria) General proposal submission (since October 2007): Submission at any time Data provision for the costs of fulfilling the user request / specific IPY handle Announcement of Opportunity Related to specific topics Special conditions Next AOs planned for synergistic use with Rapid Eye other SAR frequencies Folie 11 Institut für Methodik der Fernerkundung bzw. Deutsches Fernerkundungsdatenzentrum
Access to Terra. SAR-X data for scientific use II Accepted proposals: Creation of a proposal specific user account quota of products for the agreed purpose. priority The provision of data requires the signature of the user license agreement the list of people having access to the Terra. SAR-X data the confirmation of the corresponding funding Folie 12 Institut für Methodik der Fernerkundung bzw. Deutsches Fernerkundungsdatenzentrum
Access to Terra. SAR-X data for scientific use in IPY Join accepted proposals (requires agreement with PI): A number of proposals referring to IPY existing with different status Detailed overview within presentation of Dana Floricioiu (DLR) Submission of new proposals Further proposals possible at any time IPY proposals still without cost One coordinated proposal - to be discussed ? ? Acquisition plan is set up by Proposals and the respective ordering of acquisitions Background mission Folie 13 Institut für Methodik der Fernerkundung bzw. Deutsches Fernerkundungsdatenzentrum
Data Policy National security regulations established due to needs for international harmonization, e. g. for ITAR related issues German law providing regulations in force Satellitendatensicherheitsgesetz (Sat DSi. G) Definition for EO missions etc to be regulated by this law Need for permissions of data distribution for DLR and Infoterra Need for permission of operating mission Defining regulations about users / people having access to the data Defining “sensitive data” depending on resolution and phase information Regulating urgency of the product provision (<10 days) Folie 14 Institut für Methodik der Fernerkundung bzw.

Conclusion Data acquisition plan Is set up indirectly by scientific proposal and the corresponding ordering of data Your ordering drives what is acquired! IPY proposal and intensified use is possible and welcome Data Policy Equal share of scientific and commercial use Security regulations by law to be obeyed Folie 16 Institut für Methodik der Fernerkundung bzw.
