The catalog of SO positions was created. It is hosted on the FTP server of UNOS. The elements of SO orbits are calculated using of observational results, catalog of orbital elements is formed in TLE format and state vectors. SO ephemerides are calculated in the range ±250 revolutions from epoch of orbital elements, catalog of ephemerides in ILRS format is formed. The dependence of the ephemeris accuracy on the orbit type and prediction time is investigated by comparing the catalog of ephemerides and catalog of positions. Web site of UNOS is created on the base of domain mao.kiev.ua. It includes such information: the characteristics of UNOS telescopes, the SO parameters, the calculated orbital elements and ephemeris.
