In this paper we present experimental evaluations of cooperative ranging-based approaches in mobile positioning. Our main contribution is represented by experimental investigations of the errors introduced by the hand-grip effect on cooperative schemes among peer devices, demonstrating that by knowing in real-time the particular orientation of the MS in a controlled experimental environment, it is possible to mitigate and filter out the effect of the hand-grip on RSS measurements and consequently to maintain the beneficial effect of the cooperation in the final position estimation.
