With the increasing demand of space information, the formation control technology of multi-satellite system develops rapidly. The traditional research theory focuses only on three-dimensional state convergence characteristics of satellite system, which cannot effectively control the satellite formation from the time dimension. However, the intersatellite laser communication technology puts forward higher requirements for the timeliness and accuracy of satellite system formation. Therefore, this paper studies the timing formation control problem for the satellite system in geosynchronous orbit. By introducing the parametric Lyapunov equation, the predetermined time problem is transformed into a time-varying parameter design problem, and the formation strategy of dynamic gain adjustment and adaptive formation strategy are proposed. The simulation results show that the cluster satellite system can independently establish, switch and maintain the formation configuration at any predetermined time, providing a reliable guarantee for the stability of inter-satellite laser signal transmission in practical engineering.
