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

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，则导航解决方案可以独立于卫星通信。为此，需要一种可以在真实环境中运输和操作的绝对重力仪。TOP-GROMS旨在将量子导航传感器加速到真实世界的定位、导航和授时(PNT)应用中。TOP-GROMS的动机是迫切的问题，这些问题目前阻碍了暴露在真实世界环境中的量子导航传感器的操作，并将增强用于精确定位和导航服务的量子导航传感器的稳定性和尺寸、重量、功耗和生产成本(SWAP-C)；特别是在卫星导航服务不可用或中断的情况下。TOP-GROWS将通过包括模拟平台在内的一系列技术创新和初步试验来展示和提供解决这些问题的方案。TOP-GROWS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，该项目的成果将使量子导航传感器能够部署在移动平台上，从陆地和航空车辆到船舶、船舶和地下应用。我们建议开发一种重力仪，它采用空芯导梁，因此对运输车辆的横向运动更稳健，因为运输车辆的横向运动可能导致对比度损失。为了提高重力仪的便携性，我们采用了创新的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成形和开关系统，该系统将复杂的线圈几何形状与在多层印刷电路板中形成的导体网络相结合。3D打印超高压室的创建在拓扑上进行了优化，以最大限度地减少由磁场控制序列引起的涡流，从而大幅减小了尺寸和重量。这些方法将使超紧凑型系统对环境噪声具有强大的抵抗力，并有助于大规模生产。TOP枪将为英国量子导航界带来创新研究，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-GROWS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，以及从部件到系统的量子和替代导航产业生态系统的建立。因此，我们的结果对于重力剖面图的开发和开发至关重要。

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.
