Dynamic algorithms to control programmed turn of spacecraft

The problem of optimal turn of a spacecraft is considered. The time of turn, and also the functional having sense of the flow rate of a working medium is minimized. It is shown that the optimal solution is obtained within the class of two impulse control, such control provides the spacecraft to turn on a trajectory "of a free movement". The estimations of expenditures of a working medium for realization of the programmed turn are given.
