Abstract
The basic techniques used in satellite attitude control with on the spacecraft mass properties and their uncertainty is reviewed. Briefly considered are the methods of satellite reference and orientation in space, the rotational motion and the effects of external torques and mass unbalances. The effects of inertia characteristics on dual-spin, gravity-gradient and three-axis controlled satellites are also examined. The control system weight dependence on satellite life and performance requirements are shown for several spinning and non-spinning vehicles. These results the weight trade-off analyses which must be made in selecting the proper attitude control system for a given mission and performance requirement.
