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于现代基础架构的运作至关重要，通常由全球导航卫星系统（GNSS）（例如GPS）提供。这在某种程度上发生了，GNSS通常被描述为“无形的效用”。但是，我们目前对GNSS的过度依赖造成了很大的单点故障，因此具有重大的国家关注。 INS的准确性严格取决于其惯性传感器的灵敏度和噪声性能，目前它们被用作GNS的备份。通过利用量子叠加，原子干涉仪在过去十年的实验室中一直在推动惯性传感器噪声和稳定性的限制。但是，它们尚未在该领域得到充分证明，目前尚无足够的性能特征来提供完整的INS解决方案。取而代之的是，早期系统将使用量子和经典的惯性传感器的融合来提高所谓的量子增强的INS（Q-INS）的性能。Q-NAV项目旨在应对目前无法实现Q-INS的核心挑战，并在未来的Q-insss and Supsystems和Supsystems和Supsystems和Supsysss的未来制造中建立英国的能力。该项目的成功完成将为可部署的量子增强惯性导航系统铺平道路，该导航系统可用于为英国提供安全的定位和导航能力。
