TT2022-022 Gryo-magnetometer for Inertial Navigation Systems
The Quantum Magnetometer Market is expected to grow to US$700 million by 2025 (Research and Markets) driven by compelling value propositions in medicine, military, and geophysical applications.
Using the knowledge of atoms and atomic movement, researchers at The Australian National University (ANU) have developed one device that measures both rotational and magnetic field changes along two perpendicular axes, simultaneously, without crosstalk. This added capability does not add significant cost or size to the device as it is largely done with novel driving and analysis. We have thus developed it into an energy efficient, non-cryogrenic device for use in Inertial Navigation Systems (INS) and other high-precision magnetometer and gyroscope applications.
At the current development stage, the fundamental noise limits are competitive with the very best to atomic magnetometers and laser gyroscopy available today. The accuracy, low noise, size, energy efficiency and single product configuration is targeted toward the high-grade systems required commercial inertial navigation or defence.
- Multi-parameter: Simultaneous measurements of both rotational and magnetic fields with one device
- No interference: this design overcomes cofounding effects of rotation and magnetic field interferences with each other
- Sensitivity: Versatile, compact and state-of-the-art sensitivity
- Space Technologies
- Mobility & Transport
ANU is seeking external partners in the areas inertial navigation with interests in atomic magnetometers and gyroscopes to collaborate to advance the technology and are interested in licensing the technology for further development
