Radiation Hardness Assurance

News on Standardization of COTS Testing

The use of COTS components is increasing on mainstream projects for both cost and performance reasons. However, the use of COTS has its dis-advantages such as traceability, obsolescence, cost increase due to up-screening etc.

An ESA COTS Steering Committee has been set up in 2018 with the following mandate: “Bring together all ESA stake holders related to COTS based development, COTS end users, testing facilities and standards/specification entities in order to manage the evolution of the use of COTS in a coordinated manner in ESA’s current and future programmes, and in support to industrial requests”.

In this lecture, the basics of radiation hardness assurance will be introduced. Test methods and applicable standards for total ionizing dose, displacement damage and single event effects testing will be presented. The usage of COTS in ESA space programs will be discussed as well as ESA’s current approach and timeline on COTS. Considerations and RHA best practices for COTS will be proposed. Application examples will be presented.
