HARLEQUIN - High-Accuracy Robust deployabLE QUantum Inertial Navigation

全球导航卫星系统（GNSS）提供了一种易于获取的定时和位置数据来源。然而，GNSS容易受到干扰和欺骗，并且在亚地形和海底环境中不可用。基于航迹计算的惯性导航系统（INS）利用加速度计和陀螺仪来推断运动，而不依赖于任何外部系统。然而，没有一种基于经典物理的传感器能够达到GNSS保持所需的稳定性和精度。一种量子混合惯性系统，使用量子传感器和经典传感器的输入来测量空间运动，可以比现有的经典惯性系统提供显着的性能改进。该项目将提供一个量子-经典混合INS演示器，该演示器基于CPI TMD现有的gMOT产品——一种由USB电池供电的紧凑便携式磁光阱（MOT）。该系统将集成由mot衍生的加速度计、经典环形激光陀螺仪和原子钟，以精确测量位置变化，并将适用于海上平台。项目负责人CPI TMD技术有限公司将生产一个商业上可行的主权系统，可以大规模生产，供民用和国防最终用户使用。CPI TMD将带来他们的真空和子系统集成能力，以及来自潜在终端用户网络的强大商业驱动力，并利用英国8年来开发量子技术的供应链。

Global navigation satellite systems (GNSS) provide an easily-accessed source of timing and location data. However, GNSS is vulnerable to jamming and spoofing and is not available in sub-terrain and sub-marine environments. A dead reckoning-based inertial navigation system (INS) utilises accelerometers and gyroscopes to deduce movement without reliance on any external systems. However, no sensor based on classical physics has reached the necessary stability and accuracy desired for GNSS holdover.A quantum-hybrid INS, measuring spatial movement using the input from both quantum-enabled and classical sensors, can offer significant performance improvements over existing classical INSs. This project will deliver a quantum-classical hybrid INS demonstrator, built around CPI TMD's existing gMOT product -- a compact, portable magneto optical trap (MOT) powered by a USB battery. The system will integrate a MOT-derived accelerometer with a classical ring laser gyroscope and an atomic clock to allow precise measurement of changes in position, and will be suitable for use on a maritime platform.Project lead CPI TMD Technologies Ltd. will output a commercially viable sovereign system that can be manufactured at scale for use by civilian and defence end-users. CPI TMD will bring their vacuum and sub-system integration capabilities as well as a strong commercial drive from their network of potential end users, and leverage a UK supply chain built over 8 years developing quantum technologies.
