Abstract: Control moment gyros (CMGs) are momentum exchange devices which are considered to be good actuators for spacecraft due to their fast slewing capabilities. They consist of systems of gimballed momentum wheels. Singularities occur when, no matter how the gimbal angles are moved, the angular momentum cannot be increased in a given direction. We analyze the relationship between gimbal angles and the angular momentum for different CMG geometries to understand the different types of singularities which occur in these systems.
