论文摘要
计划在Cislunar空间（在月球表面，在月球轨道上以及在月球门的附近）使用的航天器的大型星座需要定位，导航和时机（PNT）的新解决方案。在这里，我描述了指南针（太阳系中位置意识的合并观察方法），这是一种航天器导航系统，可为Cislunar空间中大量航天器的定位提供具有成本效益的技术。 Compass将使用散发出连贯的超宽带信号的信标，该信号旨在与现有和将来的非常长的基线干涉仪（VLBI）网络互操作。使用差异VLBI，指南针将在常规VLBI观察会话期间以皮秒级的准确性快速确定干涉相延迟。因此，具有同时校准器观测值的多基线相引用的指南针 - VLBI观察值应实现次级精度横向定位和仪表水平的月球轨道轨道测定，并使用小的femtospacecraft信标和每个位置确定几秒钟的观察力。
The large constellations of spacecraft planned for use in cislunar space (on the Lunar surface, in Lunar orbit, and in the vicinity of the Lunar Gateway) require new solutions for positioning, navigation and timing (PNT). Here, I describe COMPASS (Combined Observational Methods for Positional Awareness in the Solar System), a spacecraft navigation system to provide cost-effective techniques for the positioning of large numbers of spacecraft in cislunar space. COMPASS will use beacons that emit coherent ultra-wideband signals designed to be interoperable with existing and future Very Long Baseline Interferometry (VLBI) networks. Using differential VLBI, COMPASS will provide rapid determination of the interferometric phase delay with picosecond level accuracy during routine VLBI observing sessions. Multi-baseline phase-referenced COMPASS-VLBI observations with simultaneous calibrator observations should thus enable sub-meter accuracy transverse positioning and meter level lunar orbit determination using with small femtospacecraft beacons and a few seconds of observation per position determination.
