In this paper, the decentralized fixed-time attitude synchronization problem is considered for multiple rigid spacecraft system. A multispacecraft fixed-time-based terminal sliding mode is designed, which possesses the predefined convergence time independent of initial condition. Then, the decentralized attitude control laws by employing the fixed-time-based terminal sliding mode are proposed, which can avoid the singularity and guarantee the attitude tracking errors converge to zero in fixed time. Finally, numerical simulations are presented to demonstrate the performance of the new controllers.
