Scientific paper

Technical problems involving the antennas considered for use in a communication with extraterrestrial intelligence (CETI) satellite project are discussed. The antenna system and monitoring are considered with reference to a search strategy. Topics examined include frequency range, thermal noises and deformations, Doppler shift correction, compensation of the dispersal effects, transmission time and distance, costs, and energy supply by the solar satellite power station. Attention is directed to the problems of possible perturbations of the orbit, undesirable motion of the antenna, and antenna mechanical oscillations.
