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.

例如，如果地球重力剖面的实时测量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，需要一种可以在现实环境中运输和操作的绝对重力计。TOP-GUNS 旨在加速量子导航传感器进入现实世界的定位、导航和授时 (PNT) 应用。 TOP-GUNS 的动机是目前阻碍暴露在现实环境中的量子导航传感器运行的紧迫问题，并将提高精密应用中使用的量子导航传感器的鲁棒性以及尺寸、重量、功耗和生产成本 (SWaP-C)定位导航服务；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初步试验（包括仿真平台）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计时方面的重大成功，并重点关注当前的关键问题研究挑战。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只、船舶和地下应用。我们建议开发一种采用空心导轨的重力计光束，因此更能抵抗运输车辆的横向移动，这可能会导致对比度损失。为了提高重力计的便携性，我们采用创新方法来创建高保真磁场屏蔽和线圈 - 这是基于先进的优化方法，以提供最先进的磁场整形和切换系统，将复杂的线圈几何形状与多层 PCB 中形成的导体网络。 3D 打印的 UHV 室的创建经过拓扑优化，可最大限度地减少磁场控制序列引起的涡流，从而大幅减少尺寸和重量。这些方法将使超紧凑系统能够抵抗环境噪声，此外还适合大规模制造。TOP-GUNS 将为英国量子导航界带来创新研究，并为英国保持其领先地位提供所需的优势量子和替代 PNT。此外，TOP-GUNS的多方面产业合作伙伴关系，包括最终用户和供应链开发商，将极大地有利于研究成果的传播以及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，我们的成果对于重力剖面图的开发和利用。
