We present an experimental procedure for the implementation af a matterwave rotation sensor. Recently many progresses have been achieved in atom-based Sagnac interferometry, such as improved sensitivity and elimination of dead times [1]. Differently from other experiments, in our scheme atoms are confined during all the interferometric sequence [2]. Instead of making use of free wave propagation, atomic clouds are steered around a ring trap in a controlled fashion [3,4]. This particular feature opens possibilities for miniaturization of the experimental apparatus towards the realization of compact devices.
