HARLEQUIN - High-Accuracy Robust deployabLE QUantum Inertial Navigation

全球导航卫星系统提供了一个易于获取的时间和位置数据源。然而，全球导航卫星系统易受干扰和欺骗，而且在地下和海底环境中不可用。基于航位推算的惯性导航系统（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，没有基于经典物理学的传感器能够达到GNSS保持所需的必要稳定性和准确性。量子混合惯性导航系统使用来自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导航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，围绕CPI TMD现有的gMOT产品-一个紧凑的，便携式的磁光阱（MOT）由USB电池供电。该系统将把一个MOT衍生的加速度计与一个经典的环形激光陀螺仪和一个原子钟集成在一起，以精确测量位置的变化，并将适用于海上平台。项目牵头方CPI TMD Technologies Ltd.将输出一个商业上可行的主权系统，可大规模制造，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，以及来自潜在最终用户网络的强大商业驱动力，并利用英国8年来建立的量子技术供应链。

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.
