Vulnerability Analysis of Satellite Products

Through the analysis of satellite vulnerability characteristics and the statistics of damage accidents, this paper obtains four categories of risk factors, and further expounds the four aspects of “human error”, “environmental factors”, “satellite products’ own energy source”, “assembly test equipment, real-time, tool characteristics”, reflecting the characteristics of satellite products. Considering both universality and pertinence (according to the characteristics of satellite assembly activities), it can provide necessary basis for subsequent safety analysis and evaluation. Finally, the analytic hierarchy process and fuzzy evaluation method are used to analyze the data examples and determine the judgment criteria. The corresponding matrix is obtained through the primary and secondary parameters. According to the maximum membership principle, the risk level corresponding to the largest of the five values corresponding to the membership of the top-level parameters is the result of the comprehensive risk assessment. The results show that the method is suitable for the vulnerability analysis of satellite products, and can be used for risk assessment.
