This project aims to investigate the basic science underpinning a new rotation sensing technology based on matterwave vortices. Current gyroscopes are susceptible to long-term calibration drifts, which limit their applicability on long timescales where re-calibration is not practical or possible. This project expects to build a matterwave vortex gyroscope and demonstrate that it offers unparalleled long-term stability over `classical’ gyroscopes based on mechanical and/or optical technology. This could deliver new navigation capabilities, benefitting Australia’s defence forces and nascent space technology industry, as well as enabling slow timescale precision gravimetry for mineral exploration, hydrology, and geology.

该项目旨在调查基础科学基础，该科学基于基于Matterwave Wortices的新旋转灵敏度技术。当前的陀螺仪容易受到长期校准训练的影响，这限制了其在不实用或可能不实可能的长时间尺度上的适用性。该项目预计将建立Matterwave Vortex陀螺仪，并证明其基于机械和/或光学技术的“经典”陀螺仪具有无与伦比的长期稳定性。这可以提供新的导航能力，从而使澳大利亚的国防部队和新生的太空技术行业受益，并为矿物探索，水文学和地质学延迟的时间尺度精确量化。
