Correlation analysis on telemetry data of manned spacecraft

To analyze the correlation of the telemetry data of manned spacecraft based on mathematical statistics is proposed in the paper, including correlation analysis based on correlation coefficient and correlation analysis based on stepwise regression. The correlation analysis on telemetry parameters from statistical viewpoint could lay the foundation for further analysis from principle viewpoint. The method is verified by the telemetry data of a manned spacecraft. The results show that the method could eliminate the unrelated factors effectively, reduce the blindness of the analysis, and improve the efficiency of analysis work significantly.
