TOPological optimisation of technologies for high-bandwidth atomic Gravimetry Used in Navigation Systems

例如，如果地球引力剖面的实时测量值可以与地图上的已知值相匹配，那么导航解决方案就可以独立于卫星通信。为此，需要一个可以在现实环境中运输和操作的绝对重力仪。TOP-GUNS旨在加速量子导航传感器进入现实世界的定位、导航和定时（PNT）应用。TOP-GUNS的动机是目前阻碍量子导航传感器在现实环境中运行的紧迫问题，并将增强用于精确定位和导航服务的量子导航传感器的鲁棒性和尺寸、重量、功耗和生产成本（SWaP-C）；特别是当卫星导航服务不可用或中断时。TOP-GUNS将通过一系列技术创新和包括仿真平台在内的初步试验，展示并提供这些问题的解决方案。TOP-GUNS项目将利用英国国家量子技术中心在传感器和定时方面的重大成功，并专注于当前的关键研究挑战。为了克服这些问题，该项目的成果将允许在移动平台上部署量子导航传感器，从陆地和航空车辆到船舶、船舶和地下应用。我们建议开发一种采用空心芯导向梁的重力仪，从而更坚固地抵抗运输车辆的横向运动，这可能导致对比度的损失。为了提高重力仪的便携性，我们采用创新的方法来创建高保真的磁场屏蔽和线圈-这是基于先进的优化方法，提供最先进的磁场成形和开关系统，将复杂的线圈几何形状与多层pcb形成的导体网络集成在一起。3d打印的特高压室经过拓扑优化，可以最大限度地减少磁场控制序列引起的涡流，从而大大减小了尺寸和重量。这些方法将使超紧凑的系统对环境噪声具有很强的抗扰性，并且适合大规模生产。TOP-GUNS将为英国量子导航社区带来创新研究，并为英国保持其在量子和替代PNT领域的领先地位提供所需的优势。此外，TOP-GUNS的多方面产业合作伙伴关系，包括终端用户和供应链开发商，将极大地有利于研究成果的传播和量子和替代导航产业生态系统的建立，从组件延伸到系统。因此，我们的结果对引力剖面图的开发和利用至关重要。

Navigation solutions can be made independent of satellite communication if, for example, real-time measurements of the earth's gravitational profile can be matched to known values on a map. For this, an absolute gravimeter is needed that can be transported and operated in real-world environments.TOP-GUNS aims to accelerate quantum navigation sensors into real-world positioning, navigation and timing (PNT) applications. TOP-GUNS is motivated by pressing issues that presently impede the operation of quantum navigation sensors exposed to real-world environments and will enhance the robustness and size, weight, power consumption and production cost (SWaP-C) of quantum navigation sensors used in precision positioning and navigation service; especially while the satnav service is unavailable or interrupted. TOP-GUNS will demonstrate and deliver solutions to these issues through a series of technology innovations and initial trials, including simulation platforms.The TOP-GUNS project will exploit major successes of the UK National Quantum Technology Hub in Sensors and Timing and focus on current critical research challenges. In overcoming these, the results of this project will allow the deployment of quantum navigation sensors on moving platforms, ranging from land and aviation vehicles to vessels, ships and subterranean applications.We propose the development of a gravimeter that employs a hollow-core-guide beam and therefore is more robust against transport vehicle lateral movement, which can result in a loss of contrast. To improve the portability of the gravimeter we employ innovative methods to create high-fidelity magnetic field shielding and coils - this is based on advanced optimisation methods to deliver state-of-the-art magnetic field shaping and switching systems that integrate complex coil geometries with conductor networks formed in multilayer PCBs. The creation of a 3D-printed UHV chamber that is topologically optimised to minimise eddy currents induced by magnetic field control sequences enables a substantial reduction in size and weight. These methods will enable an ultra-compact system that is robust against environmental noise and in addition lends itself to mass manufacturing.TOP-GUNS will bring innovative research to the UK quantum navigation community and provide the edge required for the UK to maintain its leading role in quantum and alternative PNT. Furthermore, TOP-GUNS' multifaceted industrial partnerships, including end users and supply chain developers, will greatly benefit the dissemination of research results and the establishment of the quantum and alternative navigation industrial ecosystem, extending from components to systems.Our results are therefore essential for the development and exploitation of gravitational profile maps.
