| Abstract: | This paper deals with the problem of skew maneuver for an Earth observation satellite using single-gambal control moment gyros ( SGCMGs ). Both the five pyramid configuration (FPC) and the pyramid configuration (PC) are considered, whenever the SGCMGs carry on several times of maneuver in one orbital cycle. Two types of CMG's steering logics are developed for both FPC and PC , so that the SGCMGs can pass through, and also escape from singularities. Simulation results demonstrate the effectiveness of the proposed attitude control system. |
