SIGMA+ - Study of Industrial Gravity Measurement Applications

点击翻译按钮获取中文摘要

This project is a collaboration between RSK and the University of Birmingham (UoB) to carry out a feasibilitystudy identifying the potential of Quantum Technology (QT) gravity sensors in geophysical surveys forenvironmental and engineering applications such as locating buried objects and finding sinkholes. This projectfeeds directly into the development of the QT gravity and gravity gradiometer sensors to ensure they takecogniscence of practical considerations in the harsh civil engineering environment. This study will expand onthe findings from the SIGMA project by focussing on the measurement and data handling challenges that havebeen identified, the isolation of signals of interst from other variations in the shallow soil, and will make thefirst ever QT gravity maps of the subsurface through careful field trials of prototype instruments. At the sametime it engages with future clients who will demand this technology to minimise their risk of unforeseenground conditions. SIGMA+ will provide a quantitative assessment of the potential real world capability of QTgravity sensors and define a specification of capability for instrument manufacturers to strive for.
