Scientific paper

The paper examines the problem of searching for a region limited by the set of initial points of optimal descent trajectories in a planetary atmosphere, from which it is possible to bring the vehicle to a given landing site either under nominal flight conditions or in the presence of disturbing factors. A general method for constructing this region is proposed, and a calculation example involving quasi-optimal control is presented.
