    Abstract: For the earthorienting satellite attitude anomaly with large angular rates without gyro measurement, the problem of the attitude rapid recovery only utilizing geocentricvector measurements is investigated. Firstly, a scale pendulum angle and its corresponding vector are defined based on the geocentric vector measurement, and a novel earthoriented attitude recovery control method is proposed integrating the scale pendulum angle magnitude inhibiting with energydissipating. Furthermore, all equilibria are obtained for the momentumbiased closedloop nonlinear system via applying the geometric approach, and equilibrium characteristic analysis indicates that the desired earthorienting stabilizing attitude state is to be the unique stable equilibrium with suitable parameter selection. Finally, the effectiveness of the proposed method is demonstrated by numerical simulations.
