Photographic position observations of Jupiter, Saturn and their satellites at Abastumani in 1983 - 84.

Photographic position observations of Jupiter, Saturn and their satellites performed with the Zeiss double astrograph at Abastumani in 1983 - 84 are discussed. The following satellites were observed: I - IV of Jupiter, and II - VIII of Saturn. The positions of Jupiter, Saturn and their satellites relative to the stars of a new reference catalogue FOKAT-YU, as well as relative positions of "satellite-planet" and "satellite-satellite" were listed. The data were treated at Pulkovo Observatory. The comparison of observational data with new theories of motions of planets and their satellites showed a good correlation within 1arcsec. Random observational errors do not exceed ±0arcsec.4. The results indicate fair astrometric qualities of the Zeiss double astrograph of Abastumani Observatory. The instrument can be effectively used for the problem of estimation of accurate coordinates of the solar system bodies.
