Taking the development of satellite test and evaluation(T E) as the practical application demand, aiming at the characteristics of multi-source and diversity of satellite equipment T E data, in order to ensure the quality of T E data, proposed a two-level data quality evaluation technology, reshapes the process of T E data quality evaluation, and evaluates the integrity, accuracy, consistency and reliability of established satellite equipment data through preliminary inspection data quality filtering evaluation. On this basis, a data quality evaluation index system is further built around the actual characteristics of satellite equipment T E data, and the data quality recheck is completed by using the analytic hierarchy process under multi factor fuzzy reasoning. On the basis of technical analysis, this paper analyzes the actual data of a certain type of satellite T E task. The analysis results show that the proposed technical method is feasible, and the two-level data quality evaluation can provide support for the different stages of satellite equipment T E tasks of performance test, combat test, in-service assessment.
