论文摘要
天气是一个地理基于空间的重力波动台任务，由三个无拖放的受控卫星组成，在一个等边三角形中，轨道半径为$ 10^{5} $ km。该星座面向白色矮人二进制RX J0806.3+1527位于黄道平面下方略微下方，并且会受到可能扭曲地层的重力扰动。在这项研究中，我们提出了优化天气轨道的合并方法，以便可以满足5年的稳定性要求。此外，我们讨论了由于轨道进动引起的探测器指向的长期长期漂移，并提出了稳定的轨道，并在月球轨道平面沿着其他六个点提出了稳定的轨道。指出了发现的一些含义。
TianQin is a geocentric space-based gravitational-wave observatory mission consisting of three drag-free controlled satellites in an equilateral triangle with an orbital radius of $ 10^{5}$ km. The constellation faces the white-dwarf binary RX J0806.3+1527 located slightly below the ecliptic plane, and is subject to gravitational perturbations that can distort the formation. In this study, we present combined methods to optimize the TianQin orbits so that a set of 5-year stability requirements can be met. Moreover, we discuss slow long-term drift of the detector pointing due to orbital precession, and put forward stable orbits with six other pointings along the lunar orbital plane. Some implications of the findings are pointed out.
