月球极区探测轨道设计

Orbit Design for Lunar Polar Region Exploration

  • 摘要: 月球后续探测工程要完成环月详查、中继以及月球极区着陆、巡视等任务,由于地面与月球南极通信条件较差,需要针对本次任务布置一颗中继星,建立满足任务需求的中继能力,完成着陆器和地面的通信。从中继轨道的选择、中继轨道与环月、着陆任务的配合等方面对月球极区探测轨道进行分析和设计,选择了周期12 h的环月大椭圆倾斜冻结轨道作为中继轨道,仿真结果表明,中继星可在轨道上运行10年不进行轨道维持,每圈轨道有三分之二的时间与月球南极通信,可为工程实施提供参考。

     

    Abstract: The mission of lunar detailed survey, lunar polar relay and lunar polar region landing will be completed in the subsequent lunar exploration project. Because of the poor communicate condition between the earth and moon polar region, a relay satellite will be launched and put in the proper orbit to set up the communication ability. An inclined and elliptical lunar orbit with frozen eccentricity and orbit period of 12 hour is selected as relay orbit after comparative analysis of different relay orbits, trajectory design of relay satellite and lunar polar region exploration mission. The results show that the relay satellite can fly more than ten years in the orbit without orbit maintenance. During the two thirds of one orbit period the relay satellite can communicate with the rover landing on the lunar polar region, which will provide reference for engineering implementation.
