A Rapid Maneuver Method with High Accuracy for Spacecraft Based on CMG and RW

摘要：

　　The mission of ground tracking satellite requires not only the ability of large angle rapid maneuver,but also the ability of attitude stability with high accuracy during and after maneuver.A rapid maneuver method with high accuracy for spacecraft based on CMG and RW is proposed to solve this problem.By use of initial quatemions and target quatemions,a minimum path trajectory tracking algorithm is designed along the instantaneous Euler rotation axis.This algorithm requires that during the accelerating stage and the decelerating stage,the torque command is assigned to CMG system; however,during the constant-speed stage and after maneuver,the torque is assigned to RW system.Mathematical simulation indicates that,compared with the situation of just using CMG,the new method endows the spacecraft with the ability of rapid maneuver with high accuracy.
