MiniAtom: Realization of an absolute compact atomic gravimeter

We present the realization of a highly compact absolute atomic gravimeter. The main purpose is to prove that atomic interferometers can overtake the current limitations of inertial sensors based on “classical” technologies for field and onboard applications. We show that the complexity and the volume of cold-atom experimental set-ups can be drastically reduced while keeping the performances close to the state-of-the-art, enabling such atomic sensors to perform precision measurements outside of the laboratory.
