The experimental results of study of a possibility of the laser beam pointing based on laser beam backscattered radiation, received by the telescope, are presented. As a pointing control signal the displacements of the energy centroid of the image of the aerosol scattering volume, formed by a laser beam, are used. The experiments were performed in the aerosol chamber with artificial aerosol of 0.5-0.6 m in size. It is shown that the laser beam pointing by such a way is possible within accuracy of a few mikroradians.
