Space robotics is characterized by its complexity. However validation on real prototype is costly and under real environmental conditions also limited. Thus the continuous virtual commission is crucial. This article describes a new approach for an integrated system- and test specification that fulfils the current ECSS standards and enables an early verification and validation of the system under development. This approach was validated on several space robotics applications but is not limited to this field and can be applied to other areas such as autonomous driving or automation.
