Questions concerned with calculations for orbit and movement of a cosmic vehicle relative to the center of mass are discussed. The significance of the selection of the section for the inertion of the cosmic vehicle, investigation of sensitivity of orbit to error, to perturbations and corrective actions is noted in the first question. The combination of simplified methodology during the first stage of orbit planning, and of more precision in subsequent ones, is suggested. The second question notes the importance of investigating the effects of gravitational, aerodynamic, magnetic, and other forces, on vehicle movement. The use of the results of angular motion calculations, along with sensitive element readings, is suggested in order to determine the angular motion of the vehicle. The importance of investigating the movement of a body with liquid-filled spaces under conditions of weightlessness is noted.
