“嫦娥五号”任务再入返回段测控布站区域确定方法

Ground Station Visible Region Determination Method in Chang’E-5 Reentry

  • 摘要: 针对再入返回任务地面测控总体分析设计中多天多条弹道地面测站布局优化及返回过程中应急情况下快速测控资源调配的问题,提出了一种基于再入段返回器飞行弹道的测站区域分析方法。建立了测站、返回器的位置与测站工作仰角之间的关系模型,在此基础上提出了对返回器可见的测站分布区域确定的具体方法。利用再入返回过程的理论设计弹道,计算了地面测站的分布区域。仿真结果表明,所提出的方法能快速获取对返回器可见的测站区域,已成功应用于“嫦娥五号”(Chang'E-5,CE-5)工程任务中,其可为再入深空返回总体设计、返回应急测控提供借鉴和参考。

     

    Abstract: A method based on the reentry trajectory is proposed for analysis the region for ground-based Telemetry, Tracking and Command(TT&C)station, aiming at the problem of multi-day trajectory TT&C station layout optimization and resource allocation in emergency TT&C in the process of the TT&C general analysis and design in reentry. Firstly, the model between the position of the station, the reentry module and the elevation angle of the station is propagated, the detail method of the calculation of the station distribution area, in where reentry module is visible, is put forward, and finally the results of the visible region of the ground station are calculated according to the theoretical reentry trajectory. The method proposed in this paper can quickly obtain the station area visible to the reentry module, which is of great significance for the overall design and of emergency control in reentry.
