ECSS-E-ST-70-11C Rev.1 – Space segment operability (15 October 2025)

Scope

 

This Standard contains provisions for the specification of on­board functions for unmanned space segments in order to ensure that the space segment can be operated in­flight in any nominal or predefined contingency situation.

This standard covers the operability requirements that typically apply to missions. Each mission needs to tailor this standard in accordance with their operational need. Based on the operational function required, tailoring implies a selection of the applicable standardised requirements and adding any mission specific requirements.

The operability of the space segment to meet mission­specific requirements is outside the scope of this standard.

This standard may be tailored for the specific characteristics and constraints of a space project, in conformance with ECSS-S-ST-00.
