| Abstract: |
| The exterior measurement data is a type of important tracking data for spacecraft’s flight status monitoring. The design and implementation of the real?time data processing software and the key processing algorithm issues under large number of measurements and multiple spacecrafts seems important. Based on the analysis of the characteristics and processing contents of the real?time processing software for exterior measurement data, a parallel processing software architecture, design method, result frame structure, implementation procedure and running model are given. After that, some key real?time calculation methods in the data processing are discussed, including the phase ambiguity resolving method, the interpolation algorithm, the frame?splicing method, the atmospheric refraction correction technology, and multipoint data smoothing method, etc. Then, an engineering solution suitable for real?time processing of external measurement data is given. The research results have certain reference value for data processing methods and processing software design. |
