Improving measurement performance via fusion of classical and quantum accelerometers

open access: yesJournal of Navigation, 2023
While quantum accelerometers sense with extremely low drift and low bias, their practical sensing capabilities face at least two limitations compared with classical accelerometers: a lower sample rate due to cold atom interrogation time; and a reduced ...

CARIOQA-PMP quantum accelerometer simulation

open access: yes
Satellite gravimetry missions have been providing a global measure of Earth's mass transport for more than 20 years. This provides insights into the solid Earth, cryosphere, ocean dynamics and hydrology. Planned NASA and ESA missions will continue this observation well into the 2030s.

Gravity field mapping using laser-coupled quantum accelerometers in space [PDF]

open access: yesJournal of Geodesy, 2021
The emergence of quantum technologies, including cold atom based accelerometers, offers an opportunity to improve the performances of space geodesy missions. In this context, CNES initiated an assessment study called GRICE (GRadiométrie à Interféromètres quantiques Corrélés pour l'Espace) in order to evaluate the contribution of cold atom technologies ...

Rotation related systematic effects in a cold atom interferometer onboard a Nadir pointing satellite

open access: yesnpj Microgravity, 2023
We study the effects of rotations on a cold atom accelerometer onboard a Nadir pointing satellite. A simulation of the satellite attitude combined with a calculation of the phase of the cold atom interferometer allow us to evaluate the noise and bias ...

Quantum-Based Relative Inertial Navigation with Velocity-Aided Alignment and Initialization

open access: yesEngineering Proceedings, 2023
Quantum sensors are expected to offer significant advantages in magnetic- and gravity-aided navigation. However, these techniques depend on the local environmental conditions and require an alternative solution to ensure high position accuracy on shorter
