论文摘要
该论文是我们先前工作的续集（Zhang等人，Phys。V.D 103，062001（2021））。对于拟议的地理基于空间的重力波检测器，例如天气，Glisa和Gadfli，重力场障碍，即，应仔细评估并在概念研究中考虑仔细评估和评估所谓的“轨道噪声”。基于天气，我们研究了频谱的效果如何通过单变量研究以不同的轨道取向和半径选择而变化，并提出了可能设置目标检测带的下限的相应滚动频率。结果，包括特殊的地静止轨道（Glisa/gadfli）和重复轨道，可以为轨道和星座设计提供有用的输入，以实现未来的中心任务。
The paper is a sequel to our previous work (Zhang et al. Phys. Rev. D 103, 062001 (2021)). For proposed geocentric space-based gravitational wave detectors such as TianQin, gLISA, and GADFLI, the gravity-field disturbances, i.e., the so called ``orbital noise'', from the Earth-Moon system on the sensitive intersatellite laser interferometric measurements should be carefully evaluated and taken into account in the concept studies. Based on TianQin, we investigate how the effect, in terms of frequency spectra, varies with different choices of orbital orientations and radii through single-variable studies, and present the corresponding roll-off frequencies that may set the lower bounds of the targeted detection bands. The results, including the special cases of geostationary orbits (gLISA/GADFLI) and repeat orbits, can provide a useful input to orbit and constellation design for future geocentric missions.
