Abstract

We report on our compact transportable cold atom inertial sensor for precision sensing of rotations. The sensor consists of a dual Mach-Zehnder type atom interferometer operating with laser-cooled ⁸⁷Rb. Raman processes are employed to coherently manipulate the matter waves. We present the latest inertial sensitive interferometer measurements and discuss the road map to reach the full potential of the sensor featuring a sensitivity of a few nrad/s/radic(Hz).
