MAO NASU glass archive encloses about 1800 photographic plates with planets and their satellites (including near 80 images of Uranus, Pluto and Neptune), about 1700 plates with minor planets and about 900 plates with comets. Plates were made during 1949-1999 using 11 telescopes of different focus, mostly the Double Wide-angle Astrograph (F/D=2000/400) and the Double Long-focus Astrograph (F/D=5500/400) of MAO NASU. Observational sites are Kiev (Ukraine), Lviv (Ukraine), Biurakan (Armenia), Abastumani (Georgia), Mt. Maidanak (Uzbekistan), Quito (Equador).
The UkrVO Joint Digital Archive of astro-plates and the newest digitized data processing services al-lowed us to form a new approach for the creation of catalogsof astrometric and photometric characteristics of the SolarSystem bodies. Given this, the main goal of this approachwas not only to complete the processing with the best possi-ble accuracy of high-quality and unprocessed earlier photo-graphic observations of the Solar System bodies but also tofind new original data from these observations.As a result, more than 6,500 new astrometric positionsand stellar magnitudes of asteroids, and 3,036 positions ofouter planets (Pluto, Uranus, Neptune, Saturn, Jupiter) andtheir satellites have been determined. Most of the posi-tions obtained from observations of large stellar surveysof the northern sky FON (Kyiv and Kitab parts) and othersurveys (MEGA, Equatorial Catalog).The number of new obtained positions of asteroids iscomparable to the total number of all positions of aster-oids obtained at the Main Astronomical Observatory ofthe NAS of Ukraine in 1949-1996. The accuracy of newpositions is higher than in traditional determinations fromphotographic observations, but it cannot be comparable tothe accuracy of modern CCD observations.Contrary to traditional classic definitions, digitized im-ages of plates have produced a large number of faint aster-oids down to 17.5 magnitudes, which were discovered inthe early 21st century. For some of them, observations areeither completely absent or not enough over the certain timeinterval preceding the moments of their official discoveries.These data can be obtained from photographic observationsonly. Based on our observations, about 300 such asteroidswere found. The collection of missing data on positionsover certain time intervals and their analysis can be usefulnot only for modern ephemeris calculations but also forstudying the evolution of asteroid orbits over time.The cooperation between UkrVO and the observatory inBaldone of the University in Latvia, astronomical and astro-physical institutes of Uzbekistan and Tajikistan make it pos-sible to expand this work by involving numerous additionalarchives of digitized observations and processing servicesand thus obtaining new original data about the Universe.
