Abstract
The spatial correlations between VLBI observables obtained from simultaneous observations at several stations are examined, specifically those that result from the common station in each two-baseline (three-station) cross-correlation of the received radio signals. It is found that the correlations are negligible and need not be considered in constructing the time delay weight matrix in VLBI geodetic parameter estimation.
