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.

本项目旨在研究基于物质波涡旋的旋转传感新技术的基础科学。目前的陀螺仪容易受到长期校准漂移的影响，这限制了它们在长时间尺度上的适用性，在长时间尺度上重新校准是不实际或不可能的。该项目希望建造一个物质波涡旋陀螺仪，并证明它比基于机械和/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，有利于澳大利亚的国防力量和新兴的空间技术工业，以及为矿产勘探、水文和地质提供慢时标精确重力测量。
