Scientific paper

A technical design of the OSIRIS two-based optical space interferometer is based on the carbon-fiber technology and on the newest Russian achievements in laser metrology and light sensors. The whole instrument was designed as a payload to the Russian Segment of the ISS and it consists of two blokes that will be brought to the ISS by transport spacecraft Progress and installed there by astronauts. Short-live devices of the OSIRIS interferometer - light sensor and metrological laser - are replaceable for fast repairs in the open space conditions. Due to the carbon- fiber strongly constructed case and to the absence of reserved devices the total mass of the OSIRIS interferometer will not exceed 250 kg. The two-based interferometer OSIRIS consists of four off-axis telescopes will have its own guide for precision pointing to the target stars. The whole instrument will use its own independent to the ISS pointing and tracking systems. It will be mounted to the RS ISS by magnetic controlled suspension device. The OSIRIS Project was admitted to the Russian National Space Program as a payload to the RS ISS at the promoted stage, and it might be launched at 2002-2003 years.
