The interferometric Sagnac phase shift can be used for rotation detection in inertial navigation. We are designing a transportable demonstrator aiming at a multi-axis inertial sensor, not only for the precise measurement of rotations but also for accelerations. This poster will give an overview of the multi-loop atomic Sagnac interferometry theory, and present a preliminary system design for the demonstrator with Bose-Einstein condensates (BECs) of 87Rb atoms.
