Guidance and Control of a Space Robot at Additional Launching and Approaching a Communication Geostationary Satellite

Abstract

The problems of putting a space robot into a geostationary orbit using a combined scheme and its approach to a communication geostationary satellite are considered. With this approaching, the robot's attitude and orbit control system uses a plasma electric propulsion unit, a propulsion unit based on eight catalytic reaction engines with pulse-width modulation of their thrust, and a gyroscopic moment cluster based on four single-gimbal control moment gyroscopes. Simulation results on the developed discrete guidance and control algorithms are presented that demonstrate their- effectiveness.
