6. Objectives

7. Objectives Technical Infrastructure: Network and Security:
An innovative end-to-end approach for validation and operational support.
Network and Security:
A flexible and secure approach for testing and support.
Configuration Control & Planning:
An environment under control.
Quality:
Improve the quality without impacting the expertise.
Engineering Public Relation
Do what you say and Show what you do.

8. End-to-End Objective Validation from the following perspectives:
Functional: validation of provided services (TM, TC, Tracking, Station M&C, …);
Performance: mission requirements increase;
stability (long duration).
Required by
OPS-O, triggered by MEX, ROS low bit rate problems;
OPS-G, more systematic validation.

9. Network Objective Simulated operational network. Required by:
Performance testing;
Error cases: bit error rates, latency, … ;
Long duration testing;
Isolated from non-operational data traffic;
Independent from operational use constraints (e.g. freeze).
Required by:
OPS-G, end-2-end representative validation.

10. Security Objective Support from external industry: Internet Access
Secure sessions (remote troubleshooting);
Established and controlled by the T.O.
Internet Access
Testing of ESA infrastructure against new developed equipment outside ESOC (e.g. timing system M&C validation);
Required by:
OPS-G to reduce costs and increase efficiency;
ESA security requirements.

11. Configuration Control Objective
Ensure the configuration of the environment:
Support various versions of subsystem;
Support various configuration of subsystem and end-2-end;
Validate hardware integration configuration to be in line with Ground-Station System Integration Standard.
Required by:
OPS-G, validation of various versions;
OPS-O, end-2-end validation of configuration changes, backward compatibility, …

12. Quality Objective Develop processes associated with: Required by:
End-2-End validation;
Security;
Configuration control;
Scheduling of resources (booking capability, visibility to users);
Pre-deployment validation.
Required by:
OPS-G
OPS-O.

13. Public Relation Share OPS-G capability with: Show what engineering is:
ESA colleagues;
ESOC visitors.
Show what engineering is:
Engineering processes;
Ground-Segment: Ground-Station, Control Centre and Network;
Data flows; …
Temporary vs Permanent Exhibitions
Short term: Poster display (e.g. the ones presented in conferences;
Long term: Explain what a Ground-Segment is?
Required by: OPS-G.
