ECSS-E-70-11A – Space segment operability (5 August 2005)

This standard has been cancelled and replaced by ECSS-E-ST-70-11C (31 July 2008).

Scope

This Standard contains provisions for the design of on-board functions for unmanned space segments in order to ensure that the space segment can be operated in-flight in any nominal or predefined contingency situation.

The requirements in this Standard are grouped in two clauses, containing general operability requirements and detailed operability requirements, respectively. The general operability requirements canbe applied to all missions, whilst the detailed operability requirements are only applicable if the corresponding on-board function is implemented.

The operability of the space segment to meet mission-specific requirements is outside the scope of this standard.

When viewed from the perspective of a specific project context, the requirements defined in this standard should be tailored to match the genuine requirements of a particular profile and circumstances of a project.

NOTE Tailoring is a process by which individual requirements of specifications, standards and related documents are evaluated, and made applicable to a specific project by selection, and in some exceptional cases, modification of existing or addition of new requirements.

To support the users of this Standard in tailoring the requirements to the needs of their particular mission, Annex B contains a table that indicates, for each requirement, the potential impact of its omission.
