2H Singularity-Free Momentum Generation with Non-Redundant Single Gimbaled Control Moment Gyroscopes
Abstract
Two objectives dominate consideration of control moment gyroscopes (CMGs) for spacecraft maneuvers: High torque (equivalently momentum) and singularity-free operations. This paper adds to the significant body of research
towards these two goals utilizing a minimal 3-CMG array to rovide 646% singularity-free momentum performance
increase spherically, compared to the ubiquitous pyramid
arrangement skewed at 54.730. Spherical 1H (1 CMGs-worth (momentum) singularity free momentum is established with
birectional 1H and 2H in the third direction in a baseline configuration. Lastly, momentum space reshaping is shown via mixed skew angles. These claims are demonstrated analytically, then heuristically, and finally validated experimentally.
