A new solution is emerging for ground-based asteroseismology with the potential opening of Dome C in Antarctica as an astronomical site. At a latitude of 75° South, many sources becomes observable without interruption for several weeks, as a space instrument is doing. However, bringing a high resolution grating spectrometer in such a site would be a heavy operation. Hence, a study has been conducted for a different type of velocity seismometer, based on an interferometer (Mosser et al. 2003), leading to the concept of a compact, monolithic instrument, without moving parts, called SIAMOIS. A single instrument of this type behind a 2-m class telescope could reach the required sensitivity to observe solar-type stars of magnitude <5, with a velocity precision of few cm s-1 after 5 days. The implementation of a robotic 80-cm telescope (IRAIT) as a first equipment could make possible the preliminary tests of this new seismometer.
