Field Ready Absolute Quantum Gravimetry (ABGRAV)

地下勘测是一个快速增长的领域（50亿美元，11%的复合年增长率），其驱动因素是建筑行业需要在侵入式挖掘、钻孔和隧道掘进之前确定现有的公用设施，如下水道、电缆、电信电缆、燃气和水管。没有这些工人很容易破坏管道和电缆，这会危及生命，造成金钱损失，并给居民和道路使用者造成严重破坏。据估计，这将使英国经济每年损失12亿英镑，并阻碍棕地的重新开发。同时，地球物理测量也广泛用于采矿工业，以确定石油储量或矿藏的位置，以及对地下水位和冰盖进行环境监测。冷原子重力法为地下测量的灵敏度提供了一个潜在的台阶变化，并大大提高了这些工业的能力。MSL的量子重力仪已经在商业环境下的发展道路上达到了重要的里程碑，2018年在全国展示会上进行了展示，最近在伦敦的一艘驳船上进行了测量。该系统的一个关键问题是它对环境噪声的敏感性，这是所有量子传感器的局限性。在这个项目中，MSL旨在通过一系列噪声补偿子系统全面解决这些问题。该项目的产出将使量子传感器在现场设置中实现灵敏度的飞跃，实现更快的商业化，并为财团和英国plc带来更快的投资回报。

Underground surveying is a rapidly growing sector ($5bn, 11% CAGR), driven by the construction industry needing to identify existing utilities such as sewers, electric cables, telecoms cables, gas and water mains prior to invasive excavating, drilling and tunnelling. Without these workers can easily strike pipes and cables, that risks lives, cost money and cause havoc for residents and road-users. It is estimated to cost the UK's economy £1.2bn p.a., and dissuades re-development of brown field sites. Concurrently, geophysical surveying is widely used in the mining industry, to locate oil reserves or mineral deposits, and for environmental monitoring of water tables and ice sheets.Cold atom gravimetry offers a potential step change in sensitivity to underground surveying, and a dramatic increase in capability to these industries.MSL's quantum gravimeter has already reached significant milestones in its development path within a commercial setting, being demonstrated in 2018 at a national showcase, and recently taking measurements on a barge in London. A key issue with the system is its susceptibility to environmental noise, a limitation of all quantum sensors. With this project MSL aim to comprehensively address these issues with a range of noise compensation subsystems.The output of this project will enable quantum sensors to make leaps forward in sensitivity within field settings, enabling faster commercialisation, and faster return on investment for the benefit of the consortium and UK plc.
