A self-maneuvering unit for an orbital worker who must perform maintenance, supply, and inspection tasks on or between space vehicles is discussed. One essential component of such a unit is a continuously acting stabilization system. This provides the worker with a stable self-oriented reference frame by which he may judge position, velocity, and acceleration. This type of stabilization can best be provided by momentum wheels which rotate uniformly in the manner of a gyroscope. Since a rotating wheel tends to remain in its plane of rotation in the absence of external forces, the capability for stabilization is provided. Likewise, since a rotating wheel tends to change its plane of rotation with the application of force moments torques, the capability for controlled rotation is provided. This report serves to develop the principles of controlled rotation and incorporate them in a feasible stabilization-rotation system.
