Proposal of a Lightened Radiation Hardness Assurance Methodology for New Space

The use of Commercial Off the Shelf (COTS) electronic components or subsystems has recently increased with new space applications. Due to the harsh constraints applicable to such projects in terms of cost and lead time, the European Radiation Harness Assurance standard for space applications [1] is not adapted. Thankfully, in New Space, reliability and availability requirements are often relaxed compared to other missions, at least at component level. That is the reason why CNES proposes a simplified RHA methodology dedicated to nanosatellites and new space applications. In the following, we present the lightened RHA methodology proposed and discuss the simplifications done.
