The researches carried out at the CrAO with the use of the ZTSh, AT-64 and RT-22 optical and radio telescopes in large international cooperation during 2004–2005 are described. The space debris is a new scientific field for the Crimean astrophysical observatory, nevertheless, the results obtained are significant. These works were arranged under project of organization of scientific sensors network for the investigation of near-Earth objects. In all, 49 GEO-fragments fainter than 16 star magnitude were detected and tracked to determine their orbital parameters and to estimate their physical characteristics. The existence of fragment clouds and a new class of the unique objects with extra-high area-to-mass ratio was confirmed. The VLBI radar experiment was arranged for few discovered fragments to obtain precise trajectory measurements and some data on fragment sizes and rotation periods.
