Methods, algorithms and programs are developed for: - optimization of launch vehicle composite trajectories, spacecraft transfers and programs on space and rocket objects movement control; - determination of space object uncontrollable movement parameters at next to last turns before atmospheric entry; - calculation of spacecraft orbital evolution in the earth's gravitational field for steady and non-steady models of earth's atmospheric density. A series of model problems are resolved using developed methods, algorithms and programs. Problems on dynamic stability of multiunit mechanical systems described by singular equations are studied, control methods to circumvent negative effects caused by singularity are proposed.
