To solve the difficult problem of multi-sources telemetry data use in spaceflight TT&C, data pretreatment procedure and data fusion method are studied in this paper. On basis of the existing telemetry data processing, a new data pretreatment procedure is designed, realizing the function of data screening, extracting and selecting. A new data fusion method based on optimal weighted is put forward as well. The algorithm and distribution principle for optimal weighted values are discussed and presented. In the end, after the data pretreatment and fusion stages, a more accurate and reliable data result is provided. Theoretical analysis and real mission data implication show that data quality after pretreatment and fusion is improved obviously. It enhances the precision of data processing, and reduces risks caused by error data. The method has great value in engineering application, and can make reference for the further research of multi-sources data processing.
