4.9.3 ALTERNATIVE OPERATION LAYOUTS WITH EDRS GSC Sentinel-2 PDGS OCD Issue 1 Revision 2 (draft) - 25.07.2010 GMES-GSEG-EOPG-TN-09-0008 page 178 of 350 Additional possible mission operation configurations are outlined here should EDRS not provide high-bandwidth repatriation services or should they not be finally sized sufficiently to support the baseline requirements.

GSC Sentinel-2 PDGS OCD Issue 1 Revision 2 (draft) - 25.07.2010 GMES-GSEG-EOPG-TN-09-0008 page 179 of 350 It is inheriting the principles of the EDRS enhanced layout while using ground-networks (or media shipment as trade-off) to repatriate the data acquired at polar stations to a mediumterm centre. According to the actual X-Band CGS set-up, RT and NRT acquisitions will be routed in priority via the OCP to EDRS enabled CGSs to take benefit of the wide multicast coverage provided through EDRS. This will ensure that the two EDRS Ka-Band stations can share the RT and NRT processing or provide for redundancy by simple configuration. 4.10 PDGS Services Portfolio The portfolio of PDGS services aims at stating all high-level services the Sentinel-2 PDGS system will offer vis-à-vis its external interfaces during operations starting at Phase-E1, using the PDGS system capabilities defined in [RD-01]. The service requirements cascade from the PDGS specific function within the overall Sentinel-2 system and, to a higher level, within the GSC to be guaranteed starting at Phase- E1 and sustained in the long term throughout Phase-E2. This chapter describes all services offered by the PDGS highlighting for each one, the scope and characteristics, the invocation mechanism and the relevant PDGS interface applicable to it.. 4.10.1 SERVICES TO PDGS STAKEHOLDERS This section describes all PDGS services dedicated to supplying Sentinel-2 data to the identified data consumers, namely: ○ End-users, including GSPs, for the supply of Sentinel-2 data products through the MMUS; ○ GSPs for the supply of Sentinel-2 products via the CDS through the CDS/DAIL I/F; ○ Local Ground Stations through the LGS commanding interface enabling the native Sentinel-2 X-Band space-to-ground real-time data reception to any authorized LGS; ○ The FOS for the supply of HKTM data received at the PDGS; ○ The general public for the on-line publishing of Sentinel-2 true-colour images. 4.10.1.1 Sentinel-2 User Services As introduced in section 4.5.2.2.1, the Sentinel-2 PDGS will offer a homogenous data access to supply Sentinel-2 generated products to all authorised users via ESA’s MMUS. Besides product access provided through a multi-mission interface, this service embeds all necessary user-support functions such as the publishing of relevant documentation and the management of a Support-Desk. 4.10.1.1.1 Service Users Service users are all registered end-users entitled to access Sentinel-2 products via the MMUS interface.
