SGS @ ESAC
 SGS refers to the ESA elements of the wider BepiColombo Science Ground Segment.
 The Science Ground Segment (SGS) is located at the European Space Astronomy
Centre (ESAC), Madrid, Spain.
 The SGS combines the functionalities of a Science Operations Centre, covering the
science operation planning and generation of consolidated payload command
requests, and the science data handling and archiving functionalities, such as the
science data pre-processing, Quicklook analysis and long-term scientific archiving.
 ESAC experience in different areas, e.g.:
– Mission planning : MEX, VEX,
ROS (automated optimization),
XMM, Herschel
– Data processing pipelines: XMM, Herschel,
Gaia and to a lesser extent VEX
– Real time archiving : Herschel

OGS @ ESOC
 OGS refers to the ESA BepiColombo Operational Ground Segment, located at European
Space Operations Centre (ESOC), Darmstadt, Germany.
 The OGS will be responsible for the operation and control of the Mercury Composite
Spacecraft (MCS) during the cruise phase as well as the MPO and MMO orbit insertion
 The OGS will be responsible for all mission
operations planning, execution, monitoring and
control activities during the science phase
 ESOC will provide a ground station network to
support telemetry acquisition, telecommand and
tracking operations during all mission phases.
 OGS
and
SGS
work
closely
together
for
everything concerning payload operations

BepiColombo ESA Ground Segment
(Mercury Science Phase) Overview

SGS Role
 Provide value added services to all involved (and thus enhance
the science return of the BepiColombo mission)
 Centralise common functions to free up resources in the
Instrument Teams
 Implement a Science Ground Segment which will allows maximum
planning flexibility, while maximising the overall mission science
return efficiency
 Data Handling and Archiving, Science Operations and Liaison
Scientist Teams

SGS Context
 So, what is the SGS responsible for?
 Science Operations Planning
• Producing the Science Operations Plan with SWG and Project Scientist
• Coordinating inputs and send to the Operational Ground Segment
• Monitoring data quality for quick corrections to the operations plan
 Data Handling
• Distributing data (labeled, packaged with auxiliary data, etc.) to Instrument Teams
• Providing Quicklook data facilities also monitoring data quality
• Supporting Instrument Teams in identifying issues relevant to science planning
• Running data processing pipelines for generation of scientific raw products
• Ensuring processed data suitable for long term archiving (with Instrument Teams)
• Definition/Design/Implementation of the BepiColombo Archive
• Archiving MPO data
• Providing access to MMO scientific data (MPO/MMO science data sharing)

Traceability Matrix (TMX)
•
•
•
•
The Science Themes Table (STT) was restructured following the
format of the JUICE TMX.
All information from the STT was transferred into the TMX draft.
The content of each level of the TMX is more or less known and at
least partially populated.
Details of the type and amount of information in each level are
currently being worked out with the SGS system design team.
•
The progressively more-detailed structure of the TMX levels will be
worked into the currently-under-design operations database.
•
From you: define a measurement and an observation for each
sensor?

Science Activity Plan & Operations
Planning
•
•
•
Issue 1.0 sent out in Oct 2012
Feedback to Issue 1.0 received from most PI teams
Feedback incorporated into Issue 1.1 circulated end of January
•
•
SAP Chapter 2 significantly reworked by the LST and PS.
Chapter 2 delivered by Harri to HEWG on 26 April for discussion.
•
The LST are preparing to update the science operations plan during the summer,
once the s/c resources are known.
•
Planning/analysis tools (EPS/MAPPS) are being updated and validated.
•
SAP 1.2 planned by Sep 2013 will be an input to the S/C Delta CDR
•
In parallel an orbit test case will be analyzed (to understand the impacts on
science operations of a highly variable orbit)

FROM you: All requests for off-pointing for operations or in-orbit
calibration and commissioning activities must be detailed in the EID-B
Hermean Environment Working Group Meeting | SGS Team | Key Largo | 16/05/2013 | Slide 11
Calibration(s), IST#2 and Flexible
downlink
On-ground calibration activities – SGS would like to be involved!
In-orbit calibration – a working group has been established which will
analyse requests for off-pointing for in-orbit calibration campaigns
a.
activities kicked off last March (meeting at ESTEC within the
frame of the SOWG);
b.
b) Next meeting expected to take place early Summer
IST#2 on ETB using EM with latest software and maybe hardware
upgrades – should be as close as possible to the FM
IST on FM can then use same specs and debugged code
Flexible downlink – how would you like to use it?

Data Handling and Archiving
Data Handling and Archiving concept document has been produced and
distributed to DHAWG members

FROM you: Provide comments and help to refine some of the open issues
 Data Management and Archive Plan: It provides a detailed description of the
strategy for the design, generation, validation, transfer and archive of MPO
science data. It also specifies policies for distributing data (within BepiColombo,
to scientific community and to general public).
FROM you: to identify the science data products (raw, calibrated, derived, etc)
and provide an estimation of the data volume of those products.

Data Handling and Archiving (cont.)
 A document on software engineering guidelines has been produced by
the SGS (presented at last DHAWG)
FROM you: Fill in the questionnaire, comments on the document
 Experiment to Archive ICDs: These are separate documents and
including detailed information about the data generated and also
information on all data deliverables, including the data flow, data
processing and analysis system, and any SW algorithms for generating
the data.
FROM you : These documents will be produced by each Instrument Team
