Query: Development of compact cold-atom sensors for inertial navigation   Inertial sensors based on cold atom interferometry exhibit many interesting
features for applications related to inertial navigation, particularly in terms
of sensitivity and long-term stability. However, at present the typical atom
interferometer is still very much an experiment---consisting of a bulky, static
apparatus with a limited dynamic range and high sensitivity to environmental
effects. To be compliant with mobile applications further development is
needed. In this work, we present a compact and mobile experiment, which we
recently used to achieve the first inertial measurements with an atomic
accelerometer onboard an aircraft. By integrating classical inertial sensors
into our apparatus, we are able to operate the atomic sensor well beyond its
standard operating range, corresponding to half of an interference fringe. We
report atom-based acceleration measurements along both the horizontal and
vertical axes of the aircraft with one-shot sensitivities of $2.3 \times
10^{-4}\,g$ over a range of $\sim 0.1\,g$. The same technology can be used to
develop cold-atom gyroscopes, which could surpass the best optical gyroscopes
in terms of long-term sensitivity. Our apparatus was also designed to study
multi-axis atom interferometry with the goal of realizing a full inertial
measurement unit comprised of the three axes of acceleration and rotation.
Finally, we present a compact and tunable laser system, which constitutes an
essential part of any cold-atom-based sensor. The architecture of the laser is
based on phase modulating a single fiber-optic laser diode, and can be tuned
over a range of 1 GHz in less than 200 $\mu$s.
