项目摘要

Accurate positioning and navigation are essential for the functioning of modern infrastructure and are usually provided by Global Navigation Satellite Systems (GNSS) such as GPS. This occurs to such an extent that GNSS is often described as the 'invisible utility'. However, our current overreliance on GNSS creates a large single point of failure and is therefore of significant national concern.Prior to GNSS, inertial navigation systems (INS) were the standard for navigation. The accuracy of an INS depends critically on the sensitivity and noise performance of its inertial sensors, and they are currently used as backup for GNSS.By exploiting quantum superposition, atomic interferometers have been pushing the limits of inertial sensor noise and stability for the last decade in laboratories. However, they have not yet been demonstrated fully in the field, and do not currently have sufficient performance characteristics for a complete INS solution. Instead, early systems will use fusion of quantum and classical inertial sensors to enhance the performance in a so-called quantum-enhanced INS (Q-INS).The Q-NAV project aims to tackle the core challenges that currently stand in the way of achieving a Q-INS, as well as establishing a UK capability in the future manufacturing of Q-INSs and their subsystems. Successful completion of the project will pave the way toward deployable quantum-enhanced inertial navigation systems which can be used to provide secure positioning and navigation capability for the UK.

准确的定位和导航对现代基础设施的运作至关重要，通常由全球定位系统（GPS）等全球导航卫星系统（GNSS）提供。这种情况发生的程度如此之大，以至于GNSS经常被描述为“看不见的效用”。然而，我们目前对GNSS的过度依赖造成了巨大的单点故障，因此引起了国家的重大关注。在GNSS之前，惯性导航系统（INS）是导航的标准。惯性导航系统的精度在很大程度上取决于其惯性传感器的灵敏度和噪声性能，它们目前被用作GNSS的备份。通过利用量子叠加，原子干涉仪在过去的十年里一直在实验室中突破惯性传感器噪声和稳定性的极限。然而，它们还没有在现场得到充分的证明，目前还没有足够的性能特征来实现完整的INS解决方案。相反，早期的系统将使用量子和经典惯性传感器的融合来增强所谓的量子增强型INS （Q-INS）的性能。Q-NAV项目旨在解决目前阻碍Q-INS实现的核心挑战，并在Q-INS及其子系统的未来制造中建立英国能力。该项目的成功完成将为部署量子增强惯性导航系统铺平道路，该系统可用于为英国提供安全定位和导航能力。
