ECSS-E-70-11A, SPACE ENGINEERING: SPACE SEGMENT OPERABILITY (05-AUG-2005)

ECSS-E-70-11A, SPACE ENGINEERING: SPACE SEGMENT OPERABILITY (05-AUG-2005)., 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 toallmissions, whilst thedetailed 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.
