火星探测器精密定轨软件研制及实测数据处理

Development of Precise Orbit Determination Software for Mars Probe and Data Processing for MEX

  • 摘要: 研发了一套具有自主知识产权的火星探测器精密定轨及动力学参数解算软件系统,介绍了软件的设计思路与基本结构。对2009年8月中国甚长基线干涉测量网跟踪的火星快车号三程多谱勒数据和相同弧段欧洲空间局的双程多谱勒数据进行了处理。结果表明,对于三程多谱勒数据,精密定轨后的残差处于0.079 mm/s的水平,轨道与比利时皇家天文台发布的火星快车精密轨道(精度20~25 m)最大差距小于100 m;对于欧洲空间局双程多谱勒数据,精密定轨后的残差处于0.067 mm/s的水平,轨道与精密轨道最大差距小于10 m。对火星快车跟踪数据的处理结果表明该软件可靠。

     

    Abstract: We develop a set of independent intellectual property rights software named MAGREAS (Mars gravity recovery and analysis software/system) to determine the Mars spacecraft orbit and solve Mars dynamic parameters. We introduce the design idea and basic structure of the software, and the three-way Doppler data of MEX (Mars express) from Chinese VLBI Network as well as the two-way Doppler data from ESA are analyzed. The results show that for the three-way Doppler tracking data, the post-fit RMS is 0.079 mm/s, and the maximum difference between post-fit orbit and precise orbit provided by Royal Observatory of Belgium is less than 100 m; for the two-way tracking data, the post-fit RMS is 0.067 mm/s and the maximum difference is less than 10 m. The results indicate MAGREAS is reliable and accurate. This software can provide reference for processing the orbital tracking data of Mars spacecraft of the upcoming Chinese Mars exploration mission.
