Abstract:We propose SILVIA (Space Interferometer Laboratory Voyaging towards Innovative Applications)，我们提出了SILVIA (Space Interferometer Laboratory Voyaging towards Innovative Applications) ，一个旨在演示三个航天器之间相距100米的超精密编队飞行的任务概念。SILVIA旨在通过集成航天器传感器、激光干涉测量、低推力和低噪声微推进技术，以实现亚微米级的相对距离控制，从而实时测量和控制航天器之间的距离和相对方向。一个近圆形低地球轨道上100米规模的任务被认为是演示SILVIA的理想且经济高效的设置，因为这种配置在小的相对扰动和低碰撞风险之间保持了良好的平衡。该任务将填补当前的技术空白，为未来的任务铺平道路，包括引力波天文台，如旨在探测原始引力波背景的DECIGO (DECihertz Interferometer Gravitational wave Observatory)，以及高对比度零位红外干涉仪，如旨在直接成像附近类地行星候选者的热辐射的LIFE (Large Interferometer for Exoplanets)。概述了该任务概念及其关键技术，为下一代高精度空间天文台铺平了道路。 Comments: | 9 pages, 6 figures
