Verification (spaceflight) - Overview

Overview

In the field of spaceflight verification standards are developed NASA and the ECSS, and to specify requirements for the verification of a space system product, such as:

• the fundamental concepts of the verification process,
• the criteria for defining the verification strategy and
• the rules for the implementation of the verification programme.

Verification is one main reason that costs for space systems are high. All data are to be documented and to stay accessible for potential, later failure analyses. In previous times that approach was executed down to piece-parts level (resistors, switches etc.) whereas nowadays it is tried to reduce cost by usage of "CAM (Commercial, Avionics, Military) equipment" for non-safety relevant units.
