Abstract : In this article, we review the basic physics of an atom interferometer. We highlight the usefulness of atom interferometers for inertial navigation due to their high phase sensitivity to both linear acceleration and angular rotation, but also the drawback that a single atom interferometer cannot distinguish between the two sources of phase shifts. We describe a design for a dual atom interferometer to simultaneously measure acceleration and rotation and we describe the current status of our apparatus.
