VLBI between sites with multiple antenna elements, fed from a common local oscillator, holds the prospect of solving for astrometric and geodetic parameters in a new way. The Cluster-Cluster observing mode allows simultaneous observations of multiple sources on the separate “sub-baselines” between sub-elements from one site to the other. The differential analysis benefits from the total cancelation of the temporal structure of the non-geometric contributions (e.g. instrumental terms and the propagation medium). We describe the current status of the analysis of observations in June 1995 using this technique with the WSRT and VLA arrays.
