The evaluation of electronic equipment hardness to space environment charged particle influence by single event effects in accordance with standard is carried out. Limitations of the current approach in radiation tolerance evaluation of modern electronic equipment are identified and its new variant of development is proposed. The stage of calculated and experimental evaluation allowing determining the radiation tolerance of functionally complex systems considering their recovery strategy is introduced. The comparative analysis of the spacecraft payload hardness obtained on the basis of the existent and proposed methods is provided.

Keywords: probability, failure, error, ionizing radiation, spacecraft, single event effects, radiation hardness, tolerance, electronic equipment, calculation and experimental evaluation method.
