Spacecraft energy storage and attitude control

The energy storage and attitude control technologies in spacecrafts are considered. The conventional technologies like electrochemical batteries, reaction wheels and control moment gyroscopes are compared to the promising Integrated Power and Attitude Control System with Variable Speed Control Moment Gyros (IPACS-VSCMG) technology. For this purpose, various energy storage and attitude control system conceptual designs are carried out, and the results are compared. Also given a simulation to show the effectiveness of an IPACS-VSCMG to carry out a roll maneuver command while its kinetic energy is converted into electrical energy and drained at the same time.
