4.10.1.5.3 Service Dependencies and Constraints
As pre-requisite, the LGS Service user shall be registered vis-à-vis the MMA as an LGS for
Sentinel-2. All authorized LGS will be reported in the HLOP with their configuration and
agreed service parameters.
4.10.1.5.4 Triggering Mechanism and Interface
The service operation will be autonomous and will systematically deliver LGS data reception
plans at a well-defined and documented interface dedicated to each authorised LGS.
4.10.1.6 Sentinel-2 True Colour Images On-Line Publishing Service
As introduced in section 4.5.2.2.3, this service provides public anonymous access to the
collection of Sentinel-2 TCIs through a dedicated web-portal.

The timeliness of new imagery updates accessible through this service directly cascades from
the high-level mission data recovery strategy on ground as settled in the HLOP (cf. 4.5.1.5).
4.10.1.6.4 Triggering Mechanism and Interface
The image publishing service will be operated by the end-users through a web-portal
remotely accessing the imagery publishing servers according to user actions.
4.10.1.7 Housekeeping Data Distribution Service to FOS
This service is dedicated to the Sentinel-2 FOS for the timely supply of Sentinel-2
housekeeping data products (S2HKTM) immediately after data reception from the
spacecrafts.
4.10.1.7.1 Service Users
The Sentinel-2 FOS is the only identified user of this service.
4.10.1.7.2 Service Characteristics
This service is entirely autonomous and will result from the X-Band HKTM operation scenario
described in section 4.5.5. Once per orbit and immediately following data reception at the
