The problems of additional launching a space robot into a geostationary orbit and approaching a geostationary satellite for its maintenance are considered. The robot's attitude and orbit control system uses an electric propulsion unit, a propulsion system based on eight electric thermo-catalytic engines with pulse-width modulation of their thrust, and a gyro moment cluster based on four single-gimbal control moment gyroscopes (gyrodines). Numerical results are presented that demonstrate the effectiveness of the developed discrete guidance and control algorithms.
