A satellite attitude maneuver method after specific failure reconstruction of a pentagonal pyramid configuration SGCMG belongs to the technical field of spacecraft attitude control, comprises a single-axis pointing maneuver strategy of a satellite after failure reconstruction of a control moment gyroscope combination part, and is suitable for a satellite which is provided with a pentagonal pyramid configuration and has a single-axis space pointing requirement. According to the designed method, by designing maneuvering initial angular momentum configuration and a target attitude, it is guaranteed that the angular momentum of the control moment gyroscope combination is in the optimal state under the target observation attitude, target maneuvering is executed in the two stages of singularity avoidance and target maneuvering, and it is guaranteed that the angular momentum of the control moment gyroscope combination does not generate singularity in the maneuvering process. The maneuvering strategy provided by the invention ensures that the satellite does not generate angular momentum singularity in the target maneuvering process, the angular momentum is in an optimal state during target observation, and for the satellite which loses the triaxial maneuvering capability due to partial failure of the control moment gyroscope, the task execution capability of the satellite is ensured, and the availability of the satellite is improved.
