Project Description

Long-range navigation can be difficult if GPS is not available (underground and underwater) or denied by jamming or spoofing. Inertial navigation can be effective for many hours, after which conventional systems tend to lose their sense of direction. Cold atom rotation sensors (‘gyros’), which use the quantum technology of matterwave interference, have shown exquisite performance in laboratory demonstrations, and prototypes are being developed for navigation applications.

This project, supported by Thales R&T UK and within Southampton’s Quantum Control group, will explore the navigational performance possible using cold atom inertial sensors, by combining characterization of the quantum device operation, data on environmental variations, and analysis of integration within an inertial navigation system. This cross-disciplinary project will thus span aspects from fundamental quantum physics to practical system design and performance. It will suit physics graduates with an interest in navigation applications, and systems engineers interested in exploiting an emerging range of quantum technologies.

Funding Notes

The 4-year studentship provides full funding, including an annual tax-free stipend of around £15,000. Students must have a relevant connection with the UK – usually established by residence – and have, or be about to obtain, a first or upper-second class degree in Physics, Engineering or a related discipline.
