基于原子干涉仪的量子传感器可以提供前所未有的准确度和精度的惯性量测量。有人提出，这种感知的巨大变化可以提供与当前基于卫星的导航系统相当的惯性导航能力。然而，传感器测量的精度并不是限制惯性导航系统精度的唯一因素。在本文中，我们探讨了惯性导航的基本限制，并解释了量子惯性传感器如何用于缓解当前经典惯性导航系统中遇到的一些问题，但不能解决惯性导航方法中固有的基本不稳定性。
Quantum sensors based on atom interferometers can provide measurements of inertial quantities with unprecedented accuracy and precision. It has been suggested that this sea change in sensing could provide an inertial navigation capability that is comparable with current satellite based navigation systems. However, the accuracy of sensor measurements is not the only factor that limits the accuracy of inertial navigation systems. In this paper, we explore the fundamental limits to inertial navigation, and explain how quantum inertial sensors could be used to alleviate some of the problems encountered in current classical inertial navigation systems, but not to solve the fundamental instability inherent in inertial navigation methods.
