Deep observations of the Galactic Center/Galactic bulge region with the INTEGRAL satellite have provided a statisticaly well-defined sample of faint persistent sources, the majority of which may be X-ray binaries with extremely low mass optical companions feeding the compact object via Roche lobe overflow. The optical emission of these low mass binary system should be extremely faint. Therefore, to make secure associations of an optical object with these X-ray sources, we require very accurate astrometric positions. We propose to obtain ``snapshot'' observations of a sample of such sources with the CHANDRA Observatory to obtain the best possible astrometric positions which will allow us to pursue follow up optical studies of this extremely rare class of objects.
