EarthCARE Programmatic Aspects The European Space Agency (ESA) has contracted Astrium GmbH for the delivery of the EarthCARE satellite and for additional system activities regarding launch campaign and in orbit commissioning. Astrium GmbH has teamed with Astrium Ltd for the base platform, Astrium SAS for the ATLID instrument, SSTL for the MSI instrument and SEA for the BBR instrument. The procurement and especially the selection of subcontractors will run under ESA's supervision in accordance with the Best practices for the Selection of Subcontractors, tailored to the needs of the EarthCARE contract. Procurement will commence after the System Requirements Review (SRR). Specific announcement of intended ITT will be published on EMITS approximately four weeks in advance to the proper ITT. 19/12/2006 Page 10
