In view of problem that bad timeliness of post processing of aerospace measurement information data analysis, put forward the method for real-time data quality analysis. According to feature data quality analysis method and aerospace measurement information, establish measurement and control information quality analysis model and quality analysis rule of standardization, reality, accuracy and reliability. Recognize rule according to requirement and customization analysis process, realize dynamic real-time monitoring pre-alarming, abnormal data capturing and failure judgment. The result in test and control net show that the method can find out problems of measurement information in collecting, transportation and processing in aerospace test. Evaluate the completion of the mission accurately. Furthermore, it has some values for other real-time data stream systems.
