Separated spacecraft interferometry missions will require that spacecraft move in a coordinated fashion to ensure minimal and balanced consumption of fuel. This paper develops strategies for determining interferometry mission plans that result in significant fuel savings over standard approaches. Simulation results demonstrate that valuable reductions in fuel consumption can be realized by combining the retargeting and imaging maneuvers required to image multiple stellar sources. Fuel-optimal imaging strategies have been developed for two-spacecraft interferometry missions similar to the proposed StarLight mission using chained local optimization methods. Based on these strategies, sampling-pattern guidelines for space-borne interferometry missions have been developed.

双航天器干涉测量任务的节油策略

分开的航天器干涉测量任务将要求航天器以协调的方式运动，以确保最小且平衡地消耗燃料。本文提出了确定干涉测量任务计划的策略，这些方法可比标准方法节省大量燃料。仿真结果表明，通过组合对多个恒星源成像所需的重新定向和成像演习，可以实现燃料消耗的显着降低。与链式局部优化方法类似，已为类似于建议的StarLight任务的两航天器干涉测量任务开发了燃料最优成像策略。基于这些策略，已经制定了星载干涉测量任务的采样模式指南。
