Radiation Hardness Assurance


COTS components in space projects: motivations and challenges

The use of COTS components in space projects is increasing for both cost and performance reasons. However, the use of COTS has its disadvantages such as traceability, obsolescence, cost increase due to up-screening etc.
In this lecture, the main motivations for using COTS in European space projects will be presented. The classifications of EEE parts and modules will be introduced. Some of the basics of radiation hardness assurance will be recalled. Lastly some of the challenges encountered during RHA activities for COTS will be presented. COTS components represent a great opportunity for space programs but their use can pose significant challenges in order to make radiation robust space systems.
