established under Sub-element 11 thereof;
- "QKD SAT'' aims to:
 • De-risk and optimise the innovative QKD Space and Ground technologies, for
cost, perf ormance, quality and security level of the services delivered globally.
 • Gain an early mover advantage by successfully implementing and deploying a
space centric QKD infrastructure and delivering QKD services offered
through optimised service delivery models and mechanisms.

to the application of Clause 31 of the GCC.
1.1.2 a) The decision process whether to proceed or not with Phase 2 shall be initiated
immediately after successful System Preliminary Design Review [so-called
here-after "S-PDR"] and at the latest at successful Payload Preliminary Design
