In this paper, we present a realisation of an on chip atomic clock using a cold cloud of Rubidium 87 atoms. This clock is based on a Ramsey interferometer with a Ramsey time around 600 ms. This is realized with large lab temperature drift during the measurement (few degrees per day) and without magnetic field shielding. We review the experimental implementation of this clock and give a full study of the known noises present in this atomic clock.
