【 摘 要 】

There is no "one size fits all" solution for verifying space avionics systems to ensure safety and mission success. This paper presents a verification approach based on MEAL and risk posture for space systems. MEAL refers to Mission, mission Environment, Application, and Lifetime of the application. In addition to the description of the verification approach, the paper also provides the awareness of the different levels of risks associated with verification tests and inspections when performed at part-, board- and box-level, and discusses the applications of the approach for flight heritage verification, commercial off the shelf (COTS) verification and radiation-effects verification.
