Core Principles & Analysis

• Uses two counterpropagating cold-atom clouds launched in strongly curved parabolic trajectories to provide a full inertial base.
• Three single Raman beam pairs, pulsed successively in three orthogonal directions, measure the three axes of rotation and of acceleration.
• It introduces a new atom gyroscope using a butterfly geometry.
