项目摘要

The Quantum Gravimetry for Earth Observation (Q-GEO) project will study the use of quantum atomic gravity gradiometers for space-based measurements.Earth Observation (EO) of gravitational anomalies on land and in the oceans can reveal activity in the hydro-, cryo-, and atmosphere. Gravity detectors in low-earth orbit can already measure Essential Climate Variables like melting of large ice masses and the reduction of ground water levels in drought affected regions. Improved performance will enable flood and drought forecasting, assessment of coastal vulnerability, monitoring sea level rise, and tracking changes in the atmosphere and oceans.Non-invasive geo-surveying of structures under the ground has a huge range of applications in civil engineering and infrastructure maintenance, as well as for mineral and hydrocarbon exploration.This project will revolve around using populations of cold atoms to provide improved accuracy and stability for gravity gradient measurements. A key challenge for any technology for use in space is the harsh operating environment that is presented on standard satellite buses. A core output of this project will be a technology roadmap for deployable space-based cold atom gravity gradiometers.The Q-GEO team will work closely with UK government stakeholders who will benefit from the improvements in Earth observation that this new range of sensors will provide.

地球观测量子重力测量（Q-GEO）项目将研究量子原子重力梯度仪在天基测量中的应用，对陆地和海洋重力异常的地球观测（EO）可以揭示水、冰和大气中的活动。低地球轨道上的重力探测器已经可以测量基本气候变量，如大冰块的融化和干旱地区地下水位的下降。改进后的性能将有助于进行洪水和干旱预报、评估沿海脆弱性、监测海平面上升以及跟踪大气和海洋的变化。地下结构的非侵入性地理测量在土木工程和基础设施维护方面有着广泛的应用，以及矿物和碳氢化合物勘探。该项目将围绕使用冷原子群来提供更高的精度和稳定性重力梯度测量。任何用于空间的技术都面临的一个关键挑战是标准卫星总线上的恶劣操作环境。该项目的核心成果之一将是可部署的天基冷原子重力梯度仪的技术路线图。Q-GEO团队将与英国政府利益相关者密切合作，这些利益相关者将从这一新系列传感器提供的地球观测改进中受益。
