Cots utilization requires a different approach to assessing the reliability of the assembly processes. A brief overview of the difference between the high rel with a high rel assembly built to ECSS standard is provided, and the approach identified in the ESA Cots guidelines for assessing the assembly processes is briefly presented.

This speech will report some recent experiences relevant to COTS used in ESA missions. The reported experiences range over different mission classes and budgets. COTS could be selected for different reasons: sometimes for the excessive cost of possible space-qualified alternatives, but in many cases for specific performances, low power dissipation, and smaller packages than the closest space-qualified alternative.

Lessons Learned on RHA on the selection of COTS components in ESA projects

In several ESA projects, the use of COTs devices has increased recently. Their selection has often been driven by the project’s need to reduce cost and maintain performance. On the other end, the RHA engineering and testing needed to support the approval of these parts have been greatly increased and often underestimated, leading to facilities overbooking and unavailability. Considering the overall RHA efforts from the beginning of the design phase and the consolidation of alternative irradiation test methods is impelling.

The Chinese Chang’E 4 mission includes a relay satellite named Queqiao, and onboard this satellite is the Netherlands-China Low-Frequency Explorer (NCLE) payload. This is a low-frequency radio astronomy instrument developed in The Netherlands by Innovative Solutions in Space B.V. (ISIS), Radboud University (RU), and Astron.

As a result, the CPPA is considered the main focal point for EEE parts. ESA, Prime contractors and Users have at their disposal one single interface which controls the overall project procurement. This concept enables a wide range of advantages divided into three different temporary stages: pre-procurement, procurement and post-procurement.
