论文摘要
天气是一项拟议的基于空间的重力波动台，将部署在高圆形轨道中。具有几乎固定取向的等边三角形星座可能主要在lunisolar扰动下扭曲。为了适应科学有效载荷要求，必须优化轨道以根据臂长，相对速度和呼吸角变化来稳定配置。在这项工作中，我们提出了一种有效的优化方法，并研究了如何通过单变量研究来改变两个主要设计因素，即轨道取向和半径。因此，可以到达相对稳定的轨道参数的范围，这可能有助于将来的精制轨道设计。
TianQin is a proposed space-based gravitational-wave observatory mission to be deployed in high circular Earth orbits. The equilateral-triangle constellation, with a nearly fixed orientation, can be distorted primarily under the lunisolar perturbations. To accommodate science payload requirements, one must optimize the orbits to stabilize the configuration in terms of arm-length, relative velocity, and breathing angle variations. In this work, we present an efficient optimization method and investigate how changing the two main design factors, i.e., the orbital orientation and radius, impacts the constellation stability through single-variable studies. Thereby, one can arrive at the ranges of the orbital parameters that are comparatively more stable, which may assist future refined orbit design.
