I investigate the idea that VLBI might be done between one antenna and itself as it moves along the Earth's orbit, provided the bandwidth is sufficiently small that the coherence time is longer than the time needed for the antenna to sweep out the baseline. Such a technique offers the tantalizing prospect of synthesizing space-VLBI-like baselines without needing a satellite, or the ability to fill in missing short baselines in EVN. However the initial result from a numerical model is that it does not work, at least for uniform linear motion, for an interesting reason.
