Orbit Determination through Cosmic Microwave Background Radiation
- 利用宇宙微波背景信号，通过机器学习回归模型估算速度
- 仅依赖CMB即可完成轨道初定轨，无需地球环境数据
- 适合深空任务或无地面支持的自主飞行场景
本研究探索将宇宙微波背景（CMB）辐射作为初始轨道确定（IOD）的参考信号。通过利用CMB的独特特性，提出一种新方法，可在极少依赖预先环境数据的情况下估计航天器速度与位置，显著提升独立于地球条件的空间任务的自主性与灵活性。采用机器学习（ML）回归模型，该方法展示出从CMB信号中推断速度并进一步确定卫星位置的能力。结果表明，CMB具备提升航天器操作自主性与适应性的潜力。
原文摘要 · Abstract (English)
This research explores the use of Cosmic Microwave Background (CMB) radiation as a reference signal for Initial Orbit Determination (IOD). By leveraging the unique properties of CMB, this study introduces a novel method for estimating spacecraft velocity and position with minimal reliance on pre-existing environmental data, offering significant advantages for space missions independent of Earth-specific conditions. Using Machine Learning (ML) regression models, this approach demonstrates the capability to determine velocity from CMB signals and subsequently determine the satellite's position. The results indicate that CMB has the potential to enhance the autonomy and flexibility of spacecraft operations.
