Compact Quantum Clocks For Precise And Autonomous Position Navigation And Timing

精确计时对于精确导航和各种民用、商业和军事基础设施服务至关重要，包括小型和大型固定和移动平台。这些包括：空间、空中、地面和海洋车辆、雷达、可靠的能源供应、用于空中交通管制的安全运输链路、用于数据网络和电子金融交易的网络服务器。所有这些都对国家的安全和稳定至关重要，因为许多系统目前依赖大型原子钟和全球导航卫星系统(GNSS)提供定时信号。该项目的目的是开发新型原子钟，这种原子钟以紧凑和自主的形式提供增强的计时功能。这项工作将产生简化的物理组件，当与最先进的飞轮振荡器相结合时，将产生高精度和稳定的紧凑型原子钟。这种高水平的稳定性使基于这些时钟的系统能够独立于外部源运行。

Precision timing is essential for accurate navigation and a large variety of civilian commercial and military infrastructure services including both small and large fixed and mobile platforms. These include: space, air, ground and marine vehicles, RADAR, reliable energy supply, safe transport links for air traffic control, network servers for data networks and electronic financial transactions. All of these are critical to the security and stability of the nation as many systems currently rely on large atomic clocks and the Global Navigation Satellite Systems (GNSS) for the timing signal. The aim of this project is to develop new types of atomic clock which offer enhanced timing in a compact and autonomous form-factor. This work will produce simplified Physics packages which when combined with state-of-the-arts flywheel oscillators produce highly accurate and stable compact atomic clocks. This high level of stability enables systems based on these clocks to operate independently of external sources.
