月球四程中继测量模式定轨定位方法研究

Research on Lunar Four-Way Relay Measurement Mode of Orbit Determination and Positioning Method

  • 摘要: 基于在月球南极地区探测因遮挡导致测控链路受限问题,设计了同时采用两种四程中继测量模式的方案,并从观测值组合及噪声水平两个方面,对双程和四程测量模式在月球探测器定轨定位中的作用进行了分析。结果表明,同时应用两种四程模型对两颗卫星的定轨精度有较好约束,中继卫星对双程模型噪声更敏感,低轨卫星和着陆器的噪声敏感情况与四程观测值数量相关,着陆器的定位精度与两颗卫星的定轨精度相关,可为中继测量模式在探月工程四期的应用提供参考。

     

    Abstract: To deal with the limitation of the measurement and control link caused by occlusion in the detection in the lunar south polar region, a scheme of simultaneously applying two four-way relay measurement models was designed and the role of two-way and four-way measurement models in the lunar probe orbit determination and positioning in terms of the combination of observations and noise level was analyzed, The results show that simultaneous application of the two four-way models has better constraints on the orbiting accuracy of the two satellites, the relay satellite is more sensitive to the noise of the two-way model, the noise sensitivity of the low-orbit satellite and the lander is related to the number of four-way observations, and the positioning accuracy of the lander is related to the orbiting accuracy of the two satellites, which can provide a reference for the application of the relay measurement model in the fourth phase of the lunar exploration project.
