The observation data for artificial celestial body 43096, which had beenobtained during 2006-2012 within the framework of international project "TheScientific Network of Optical Instruments for Astrometric and PhotometricObservations" - International Scientific Optical Network (ISON), wereprocessed. The Keplerian elements and state vector as of 24 November 200601:55:50.76 UTC were determined. The numerical integration of the motionequations was performed accounting for the perturbations due to the polarflattening of the Earth, Moon and Sun, as well as the solar radiation pressure.Based on the numerical model of a motion in the near-Earth space that accountsfor only the most powerful perturbations, a new method for de-orbitingartificial celestial bodies from high altitudes is suggested. For the firsttime such a considerable amount of data over long time intervals was gatheredfor the objects with high area-to-mass ratio that enabled to determine theirspecific characteristics.
