摘要：A spin-stabilized body having deployable solar panels or appendages ismodified by making the deployment mechanism capable of partial retraction andextension from the normal deployed position on an individually commandable bais. Thespin axis of a free spinning body is dependent upon the location of the center of gravitywithin the body rather than by external bearing or support points as with a restrainedspinning body. However, mispositioning of the center of gravity of the spacecraft maycause misalignment of the spin axis with respect to the geometric axis, thereby causingdynamic imbalance which is observed as body wobble. Such wobble can be minimized byoffsetting the center of gravity of the panels or appendages from the center of gravityof the spacecraft in the axial direction and making the deployment mechanism for thepanels or appendages capable of partial retraction and extension in the radial directionon an individually commandable basis.
