Newly designed space astrometric instrument, SIM-Lite, is based on six meters baseline with 50 cm aperture in the visual spectrum. Significant cost savings of SIM-Lite will keep most of capabilities of SIM-PlanetQuest for search of the Earth-like planets. In particular SIM-Lite will play a crucial role for study of galactic black holes and neutron stars in the foreseeable era of GAIA mission, which will be launched near the year 2013. Because of tiny signatures and large distances of black hole binaries, the SIM-Lite study developed a special observation scenario (Modified Narrow-Angle mode) which can provide mas resolution and distance measurement horizon of 10 kpc. This work demonstrates error estimates of observations of galactic black holes and neutron stars with SIM-Lite. Some difficulties in determination of their physical parameters with traditional techniques are analyzed. Many controversial issues on study of black holes and neutron stars are discussed by comparisons between space interferometry and other techniques.
