We investigate the issue of whether an optical interferometer with baselines long enough to resolve details of a geostationary satellite can be phase stabilized. We conclude that it is possible to phase such an interferometer with shorter baselines using the techniques of baseline and wavelength bootstrapping, and that these shorter baselines are not so short as to make the instrument impractical. We conclude by showing the trade-off between the number of telescopes needed to phase the longest desired baselines and the diameter of those telescopes.
