Requirements for COTS components usage on JAXA

Due to its advanced performances and cost saving, use of COTS components has been considered in the applications not only for the “NEW SPACE” satellites but also for JAXA’s spacecraft. JAXA has also been examining the possible use of COTS components and clarifying the conditions and specifications. As an outcome of the examination, we established four kinds of “Handbook of the Use of Commercial EEE Parts in Space Applications” which consists of the conditions and evaluation methods for each of four classified mission criteria for the purpose of utilizing the COTS components.
