This collaboration will open an adventurous new application for quantum sensing with wide reaching applications in the environmental sciences. We are aiming for improving the reference frame used by researchers in climate science to allow higher precision climate data to be collected, better models to be made and improved evidence for political decisions to be generated. As stated by the UN: "The Global Geodetic Reference Frame (GGRF) is the foundation for evidence-based policies and decisions, it underpins the collection and management of nationally integrated geospatial information and is used to monitor our dynamic Earth. Thus, the GGRF has direct societal relevance." This is the pivotal element we are targeting in this project.In more detail, we are using the latest developments in quantum sensors and perform research into making them sufficiently robust to achieve world-record precision inside the UK Space Geodesy Facility in Herstmonceux. In parallel we will research into the tools to use the continuous stream of precise gravity data from the quantum sensor to better understand the tide models and other effects influencing the measurements defining our geodetic reference frames.

此次合作将为量子传感开辟一个富有冒险精神的新应用，并在环境科学领域产生广泛的应用。我们的目标是改进气候科学研究人员使用的参考框架，以收集更高精度的气候数据，制作更好的模型，并改进生成政治决策的证据。正如联合国所说：“全球大地测量参考框架（GGRF）是基于证据的政策和决策的基础，它支持国家综合地理空间信息的收集和管理，并用于监测我们动态的地球。因此，GGRF具有直接的社会相关性。”这是我们在这个项目中瞄准的关键要素。更详细地说，我们正在使用量子传感器的最新发展，并进行研究，使其足够坚固，以在赫斯特蒙苏的英国空间大地测量设施内实现世界纪录的精度。与此同时，我们将研究使用来自量子传感器的连续精确重力数据流的工具，以更好地理解潮汐模型和影响定义大地测量参考系的测量的其他效应。
