The obtaining of the optical positions of ICRF sources, of Solar System bodies, of comets, of parameters of Earth rotation and of circumstances of the occultation and eclipses are an aim of this research work. The observations of ICRF sources on the reflector AZT-8 with CCD camera and the position observations of the Solar System bodies, of comets, of occultation and eclipses are a method of research. The preliminary values of orientation angles between ICRF and optical systems what we used as reference systems of our observations were obtained during 2002 year. A new interpretation of the coordinate differences between optical and radio systems is proposed. A catalogue of position and proper motions of about one million reference stars in the areas containing extragalactic sources is constructing. 174 time differences UT0(X)-UTC were obtained. The processing of the position observations of Solar System bodies is executing. The list of brightness outbursts of 8 comets and catalogue of the photometrical parameters of light curves of 37 comets were constructed. The observations obtained using meridian circle of AI KhNU during the eighties years are processing for constructing of differential positional star catalogue. The modern astrometric parameters for stars of catalogue by Glise were gathered. The results of this research work partially were published, partially were prepared for publication, and partially are in the analyze stage. These results can be given for using to all interested organizations and professionals in astrometry, celestial mechanic and star astronomy in Ukraine and abroad.
