Could Cold Atom Interferometry Sensors be the Future Inertial Sensors? – First Simulation Results

authored by: M. Bochkati, S. Schön, D. Schlippert, C. Schubert, E. Rasel
Abstract: Quantum technology have attracted strong interest in recent years thanks to its extreme sensitivity to inertial forces and its strong immunity to drifts compared to conventional mechanical sensors. This paper introduces cold atom sensors as six-axis inertial sensors from the engineering point of view. In order to highlight the potential of this technology as needed for inertial navigation, a strapdown closed-loop-simulation has been developed. Furthermore, we present an error model for quantum sensors that includes terms such as quantum shot noise and phase noise of the reference laser. Considering this inherent stochastic characteristics, we made also a comparison with other conventional inertial measurement units. The analysis shows that quantum sensors with the same sensitivity as of for static measuring local gravity can determine their position with accuracy of one-meter level even after one hour, while other quantum sensors with less sensitivity exhibit for the same duration an amplitude up to 1 km, similar to conventional sensors.
