Field Ready Absolute Quantum Gravimetry (ABGRAV)

地下勘测是一个快速增长的行业(50亿美元，复合年增长率为11%)，原因是建筑业需要在侵入性挖掘、钻探和隧道施工之前确定现有的公用事业，如下水道、电缆、电信电缆、天然气和自来水管道。如果没有这些工人就可以很容易地罢工管道和电缆，这将危及生命，花费金钱，并对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。与此同时，地球物理测量被广泛应用于采矿业，以定位石油储量或矿藏，并用于地下水位和冰盖的环境监测。冷原子重力测量提供了对地下测量灵敏度的潜在阶梯变化，并大幅提高了这些行业的能力。MSL的量子重力仪已经在其商业环境中的发展道路上达到了重要的里程碑，2018年在全国展示，最近在伦敦的驳船上进行了测量。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。通过这个项目，MSL的目标是通过一系列噪声补偿子系统全面解决这些问题。该项目的输出将使量子传感器在现场环境下的灵敏度方面实现飞跃，从而实现更快的商业化，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.
