This paper revisits a class of Earth-orbiting interferometric observatories introduced previously and reviews the general procedures to achieve wave-number plane coverage. The effect of eccentric spacecraft trajectories and gravity field J ₂ perturbations on wave-number plane coverage are considered. Conditions for complete wave-number plane coverage are found for certain classes of orbit perturbations. This analysis leads to design criteria for interferometric observatories that ensure wave-number plane coverage as a function of perturbation strength.

轨道变化和J ₂扰动对一类地球轨道干涉观测站的影响

本文回顾了先前介绍的一类地球轨道干涉观测站，并回顾了实现波数平面覆盖的一般程序。考虑了偏心飞船的轨迹和重力场 J ₂扰动对波数平面覆盖的影响。对于某些类型的轨道扰动，找到了完整的波数平面覆盖范围的条件。该分析得出了干涉式天文台的设计标准，该标准确保波数平面的覆盖范围是摄动强度的函数。
