High-BIAS2: High-Bandwidth Inertial Atom Source & Sensor

使用天基卫星信号的导航是英国许多关键技术的基础。大多数先进的导航技术依赖于来自全球导航卫星系统（GNSS）网络的信号，以便在长距离上保持准确。这些信号的丢失会导致导航系统不稳定，并且在操作期间位置和方向估计越来越不准确。例如，2018年，由于军事演习的信号“干扰”，挪威海岸附近的几个客运航班失去了GNSS信号。此外，“欺骗”或故意发送错误的引导信号已被证明是一种阴险的网络武器，可以故意误导和欺骗货船或客船。随着系统的自动化程度不断提高，全球导航卫星系统信号丢失的后果急剧增加，可能包括财产损失，在极端情况下甚至包括生命损失。本地机载仪器可以提供测量，以稳定当前的导航系统技术，而无需GNSS信号。基于量子技术的传感器有可能在很长一段时间内为导航系统提供稳定性，因为它具有对运动的高灵敏度与对周围环境变化的极好隔离的独特组合。High-BIAS 2将展示量子旋转传感器在没有GNSS信号的情况下稳定飞机制导系统方向的能力。使用量子技术的本地稳定将减少导航系统对GNSS的依赖，并提供针对信号丢失、干扰和欺骗的保护措施，以提高安全性和可靠性。

Navigation using space-based satellite signals underlies many critical technologies across the UK. Most advanced navigation technologies rely on the signals from networks known as the Global Navigation Satellite System (GNSS) to remain accurate over long distances. Loss of these signals result in an unstable navigation systems and increasingly less accurate location and direction estimation during operation.GNSS signals may be lost accidentally from criminal activity or due to military action. For example, in 2018 several passenger flights off the Norwegian coast lost GNSS signals due to signal 'jamming' from military exercises. In addition, 'Spoofing' or deliberately transmitting false guidance signals has been demonstrated as an insidious cyberweapon that can deliberately mislead and fool cargo or passenger vessels. As systems are increasingly automated, the consequences of the loss of GNSS signals dramatically increase and may include loss of property, or in the extreme case, loss of life. Local on-board instruments can provide measurements to stabilise current navigation system technology without GNSS signals. Quantum technology-based sensors have the potential to provide stability to navigation systems over long periods of time due to the unique combination of high sensitivity to motion with superb isolation from changes in the surrounding environment. High-BIAS2 will demonstrate the ability of a quantum rotation sensor's ability to stabilise the orientation of aircraft guidance system in the absence of GNSS signals. Local stabilisation using quantum technology will decrease the reliance of navigation systems on GNSS and provides a measure of protection against signal loss, jamming, and spoofing to increase safety and security.
