Research on evaluation model of satellite health of space launch site based on parameter statistics

Abstract In order to evaluate the health status of the satellite before launch at the space launch site, a satellite evaluation model based on parameter statistics is proposed. By analyzing the satellite test process, the general test items are obtained. The weight factor of the importance of the test item through scoring is set by multiple experts. By subdividing the qualitative and quantitative evaluation items and constructing the calculation model of the healthy degree and stability degree, a set of evaluation methods for the stage healthy degree of the satellite launch site is obtained. After many practices and revisions, the research results can quantitatively evaluate the overall health status of the satellite at the launch site stage, provide a decision basis for whether the satellite meets the launch conditions before launch, and effectively support the satellite test and evaluation work.
